Şükrü Ertürk

Born in 1947 in Şebinkarahisar, Giresun, and working at the Central Bank of the Republic of Türkiye between 1977 and 2003, the first work of the engraving artist Şükrü Ertürk was the composition of children offering flowers to Atatürk on the back of the 7th issue 10 Lira banknotes printed in 1979, the International Year of Children.

Later, he produced many landscapes and patterns such as the Mehmet Akif Ersoy portrait, the Mevlana Museum on the 7th issue 5,000 Lira banknotes, and the view of the ancient city of Ephesus using the intaglio (taille-douce) technique, which is directly hand-engraved on copper or steel plates.

 

Sukru Erturk, who was an observer in the production process of the plates of 100,000 Lira banknotes ordered abroad, produced a portrait of Ataturk on tracing paper in 17 days, when he returned to Ankara, he transferred the portrait onto a steel mold over a period of 4 months, working 4 to 5 hours a day.

The portrait was based on a photograph taken by Cemal Isiksel and a result of a through and detailed archive study. It was later used on banknotes of 100,000 to 20,000,000 Lira value of the 7th emission. He also engraved the portrait used on the 50 and 100 Lira banknotes of the 8th emission.

The engraver, who produced 15 separate Atatürk portraits for the Banknote Printing House, has his name engraved as Ş.ERTÜRK on some of the engravings used on the banknotes. (*42, p. 144 & 177).

Şükrü Ertürk, who studied at Sivas High School, continued his education at the Department of Art and Craft Teaching at the Gazi Education Institute in 1966. After working as an art teacher at the Diyarbakır Dicle Primary School between 1969 and 1971. He worked as an assistant at the Gazi Education Institute Art and Craft Department between 1974 and 1977.

Şükrü Ertürk, who met with executives of the Banknote Printing House who Gazi Education Institute in 1976, learned that the printing house needed an engraving artists. Later he passed the admission exams and started working as an engraving artist at the Banknote Printing House.

In 1986, he visited the workshop of Prof. Trento Cionini, who produced the portraits on Italian banknotes, with Mustafa Çakırcalı. Prof. Cionini was also an apprentice of Mario Baiardi. Sukru Erturk speaks of about Baiardi: “I never met him, but the engraving portraits he made became my second teacher.”

The artist also created the designs for many stamps.

Şükrü Ertürk tells about the first time a picture he drew was used on a stamp:

“I was in the senior year of Sivas High School in 1966. My art teacher Emrullah Bulurman came to me and tasked me to draw the Şifahiye Madrasah. I was so excited that I even forgot about the final exams in the first days of June. My drawing would be printed on a stamp, so I was overjoyed. I climbed atop the balcony of Çifte Minaret across from Şifahiye Madrasah and made a draft drawing. Then I made a clean copy, found my art teacher, and together we went to Sivas Governor Vefik Kitapçıgil. The governor offered us tea. I don’t remember what else he said. Then My teacher and I left the office.

…

Later when I was in the second year of Gazi Education Institute in 1967, I attended the meeting of the Ankara Sivas Association. I learned from the association president that they had printed a stamp for Şifahiye Madrasah. The next day, I went to the big post office in Ulus and inquired about the stamp. They forwarded it to the relevant unit. I bought 5 stamps. Finally I had one in my hand.

I learned about the First Day Cover and other detils during my duty at the Banknote Printing House when I was the representative in PTT’s stamp competitions. The stamp department manager Halil Say, whom I love very much, had these stamps made for me. I remember him with respect and gratitude.

I met Metin Bey, who worked in the film department at the Ajans Türk Printing House where the stamp was printed. When my drawing was reduced to the size of the stamp, many fine lines could not be printed. I had no knowledge of stamp printing when I made the drawing. Metin Bey retouched these lines. I wish him a healthy life if he is alive and mercy if he has passed away.”

 

Şükrü Ertürk defines banknotes as “functional printwork” and he has also been working on exlibris since 1997. He has produced bookplates for Prof. Hasip Pektaş, Müjde Ayan, Luc van den Briele, Benoit Junod and Prof. Dr. Aziz Sancar. The most prominent element in his exlibris, which have similarities with banknote portraiture, is the portrait of the owner.

Selahattin Tuğa (1945 ~ 2023)

Selahattin Tuğa, one of the engraving artists of the Central Bank of the Republic of Türkiye, has his name imprinted as S.TUĞA on the Mustafa Kemal Atatürk portrait and the Bosphorus view on the sixth issue 1.000 Lira banknotes. (*42, p 133).

He is also the engraver who produced the Atatürk portraits on the seventh-edition 10 Lira and 5.000 Lira banknotes.

 

 

Selahattin Tuğa was born in Diyarbakır in 1945. He completed his primary and secondary education in Diyarbakır and graduated from the Decorative Arts Department of the Istanbul State Academy of Fine Arts in 1966.

As a student at the academy, he engraved pictures and portraits on copper plates. Due to these engravings, he was recommended to the Banknot Printing House engraving workshop and after the entrance exam, he started working at the CBRT Banknot Printing House engraving workshop in 1966. During his internship, he received his first information about the taydus (taille-douce, soft carving) engraving technique from Polish engraving artist Jan Piwczyk.

Instead of direct engraving by hand, he transferred the linear portraits onto copper plates via a photomechanical method, etched them with acid and used the deepening method with engraving pens.

In the second half of the 1970s, he made the engraving of the portrait of Atatürk on the front of the E-6 series 1.000 TL banknote, and the Rumelian Fortress Bosphorus view on the back, including the Bosphorus Bridge. The graphic design of the banknote was made by Mustafa Üstün.

When preparations for the E-7 series small-sized banknotes began in 1978, he produced the Atatürk portrait on the 10 Lira and 5.000 TL banknotes of the of the E-7 series.

In 1985, he made the front and back graphic designs of the second series of the E-7 5,000 TL. He served as assistant manager between 1979 and 1990 and then served as a consultant until his retirement.

Selahattin Tuğa, who also designed countless National Lottery tickets, is also the designer and engraver of many stamps *1. Atatürk portraits on stamps of various years, the portrait of İsmet İnönü, and the “Turkish Celebrities” series of 1992 and 1993 are few of many.

 

In addition to these works, he engraved portraits on copper plates on decorative items. He also made watercolor paintings of the subjects on the front of the National Lottery tickets, and supervised the color separation, mold and printing stages of these tickets printed in the banknote printing house.

Selahattin Tuğa, who exhibited Atatürk portrait engravings and oil paintings in his personal exhibitions, passed away in 2023.

İsa Avni Kumuk (1934 ~ 2017)

Isa Avni Kumuk, was born in 1934 in Samsun to a family of Caucasian descent. He was involved with his family business of jevellry-making at the early age of six. He was quite interested and competent in maths during elementary school and and was even nicknamed Pisagor (Pythagoras). after his graduation from high school in 1953, he started his own workshop at the Grand Bazaar as a jevellry-maker and engraver. He was admitted to Istanbul Technical University as the 12th applicant.

He worked for the Turkish State Mint between 1964 and 1976  first as a technical personnel, later as the head of engraving workshop and technical consultant. During his service, he was appointed to examine the Spoonmaker’s Diamond to authenticate and measure its dimensions.

He designed many circulation and commemorative coins after 1970. His technique was compared to Giampaoli‘s.

50 Kurus piece released in 1971 was his handiwork. After visiting an exhibition of traditional Anatolian clothes, administrators of the mint asked him to come up with a portrait of a woman in traditional Anatolian head dress. The owner of said exhibition Sabiha Tansug was photographed in the Ankara Headpiece, but in order not to portrait any significant person, Avni Kumuk cut out her face and completed the portrait with an imaginary average Turkish woman.

 

Around 1976, the head of the State mint – also a prominent poet Cemal Süreya –  was instructed to decommission old machinery of the mint. Avni Kumuk convinced him to keep the machinery for display.

After his work at the Mint had ended, in 1982, he started his own company called International Goldart İstanbul, and produced over 700 medals, badges, pins and emblems ordered by several private companies and Turkish Numismatics Association. He received several awards by Turkish and international, private and public institutions.

Commemorative and circulation coins he designed and produced:

  • commemorative medallion for the inauguration of Haliç (Golden Horn) Bridge
  • medallion commemorating Saudi King Faisal’s visit to Türkiye

Avni Kumuk was also interested in painting, he was not only a skillful artist, but also a competent engineer. After the intervention to Cyprus by Turkey in 1974, he contributed to complicated parts the defence industry needed and that had to be domestically produced.

He was a member of the industrial advisory committee of ITU Mechanical Engineering Faculty. He assisted many public and private companies with their intricate designs of parts and dyes.

Father of 2 sons, Avni Kumuk worked until his last minute with the principle of giving back to the society.

Pietro Giampaoli (1898 ~ 1998)

Portrait of Atatürk by P. Giampaoli

Giampaoli was as a consultant to the Turkish State Mint and was the designer of the Ataturk effigy on the coins starting with the 1 Lira of 1957.

Same portrait was also used on the 10 Lira of 1960 silver commmemorative 10 Lira pieces.also on the 25.000.000 coin minted in 1998 as part of the 75th anniversary of the republic(*27, Page. 183).

He worked at the Italian Mint between 1936  and 1963. designed many Italian coins as well as medals and coins for Vatican, San Marino and Malta. He consulted Germany, France, Spain, Israel and Tunisia.

In 1957 he was invited to Turkey for renewing the coinage. He studied the works in the museums and monuments of Ankara and Istanbul for inspiration. Rather recent auction pieces indicate that he also worked on 25 Kuruş coins bearing Ataturk’s portrait but eventually the figure of an Anatolian woman carrying an artillery shell was used for those coins. His signature in its Latinized form (J. Pavlvs) can be seen below the portrait.

It should be safe to assume that he is responsible for the designs of coins produced at least until 1964 when Avni Kumuk started to work for the Turkish State Mint. The similarity between the 5 Kuruş piece from 1958 and the Italian 20 Lire coin of the previous year is strong evidence to this assumption.

There are auto-portraits of Giampaoli on medals(*1) where his name is Latinified. The page describes his reasoning for using thistle on his self medals as “In the language of flowers and plants, the thistle symbolizes solitude and isolation and this meaning is due to the tendency of this plant to grow in inaccessible places. An ability to make one’s way through difficulties – yet “not without effort”, indeed.”

His brother Celestino Giampaoli also was affiliated with the Turkish State Mint (*2) during the period which acmonital (Acciaio Monetario Italiano / Italian monetary steel) was used for Turkish coins. It is a variant of stainless steel that is harder than silver or cupronickel hence requires specific machinery and expertize for processing.

Percy Metcalfe (1895 ~ 1970)

Percy Metcalfe

His name is first mentioned in Turkish numismatics literature as “Sculptor of the London Mint; Mr. Medkaley“ in the 1955 Catalogue by Turkish numismatist and actor Behzad Butak.

Behzat Butak quotes “Mister Medkaley” from a proceedings report of GNAT (Grand National Assembly of Türkiye) from 1944.

(While the forms of the new Republican gold coins were being discussed, Finance Minister Fuat Ağralı elaborates that Metcalfe was invited for the effigy of Mustafa Kemal Atatürk and that he also made an effigy of İsmet İnönü. Upon criticism on why a foreigner was tasked to create the president’s effigy, Metcalfe’s skillset as a coin engraver is emphasised) His name is misspelled most probably due to a transliteration error.

Royal Mint’s involvement with the Turkish coins, dates back to 1933. In September of that year, Deputy Master and Controller of the Royal Mint, Sir Robert Johnson visited Istanbul and the capital Ankara. He had learned that the Turkish Gov’t was planning of minting new coins with the new alphabet, hence he offered Royal Mint’s services to the Turkish Government. But was not successful in securing an order for minting the new coins. However, the relations between the two mints remained active and Percy Metcalfe visited Turkey in 1935 (*Royal Mint Annual Report of 1934, Page 17).

He was meant to produce an effigy of Mustafa Kemal Atatürk, however he was requested to work on designs for the whole set of six coins.

Turkish circulation coins that bear Metcalfe’s designs:

  • 50 Kuruş 1935 ~1937
  • 25 Kuruş 1935 ~1946 (The 25 Kr pieces minted between 1944 to 1946 retained the same reverse as Metcalfe designed, however their obverse was changed to a crescent and star)
  • 10 Kuruş 1935 ~1940
  • 5 Kuruş 1935 ~1943
  • 1 Kuruş 1935 ~1944 (after 1938, these coins were converted into an undulated form)
  • 1 Lira 1937 ~ 1939
  • 1 Lira 1940 ~ 1941

Metcalfe’s family donated some of his work to the British Museum. Among those, there are the early drafts of the 1935 coins’ designs:

The newspapers of the period, indicate that several coin designs were considered at the time. 50 Kr piece was initially a variant of the 1934 100 Kr piece by Ali Cemal Bey. However, eventually Metcalfe’s designs were used; probably for consistency within the set.

 

RMAC papers of the Royal Mint have a record of a 1 Lira model depicting a stylized art-deco wolf from 1935. Around that time, the denomination of 100 Kurus was being changed as 1 Lira.

The models of the said design are kept by the Royal Mint Museum archives. Records show that it was criticised in-house (RMAC Papers dated 31/10/1935) and was minted only in a couple of samples for the evaluation.

Grey Wolf was indeed a Turkish symbol and was used on some of the first banknotes. It was even considered to be a main figure as an emblem for the Turkish Republic. However, Atatürk rejected that idea, hence such coins were never minted.

Royal Mint Annual Report of 1938 also mentions (*page 16) that Metcalfe won a contest for the new gold coins’ design but Sir Johnson states that he believes after Ataturk’s death those coins would probably not be minted.

Yet, Royal Mint Museum holds models of the effigy of İsmet İnönü (second president of the Turkish Republic), and the gold and silver coins minted after 1940 bear that effigy by Metcalfe.

In the 20th issue of the Anatolian Numismatic Bulletin, Mr. Nurüddin Gürpınar, in his article titled “Cumhuriyet Altınlarımız” (Our Republic Gold Coins), also provides information about the artist whose name was mentioned during the Turkish Grand National Assembly discussions regarding the Gold Coins bearing the effigy of President İsmet İnönü.

 

Form comparison between 1938 second type 1 Kr and Egyptian 5 Milliemmes

1 Kurus pieces minted between 1938 and 1944, were in an undulated form so that they wouldn’t be confused with the silver 25 Kr pieces of the same diameter. Said coins resemble the coins of Iraq and Egypt, which were made by Metcalfe. This could be interpreted as the cooperation between the British and the Turkish Mints was still active at the time.

 

 

 

 

 

 

 

 

 

 

 

Percy Metcalfe, served in the Royal Mint from 1924 to 1948. Effigies of King George VI and many other nations’ rulers were his handywork. among his most famous were the Barnyard Set made for Free Irish State.

As a new dominion, Free Irish State considered having its own currency. For this purpose, an international competition was held in 1926. among 66 submissions, Metcalfe’s designs were selected. The animals, which some are related to hunting and some to farming, were assigned face value based on their status; the horse being the noblest and the woodcock being the humblest.

At first there was significant criticism that a nation seeking independence from the English rule is now going forward with coins “designed by an Englishman, denominated in the English way, and made at the English mint“. However, as Nobel laureate Yeats puts it “the coins have been designed to please those who look longer at each coin than anybody else; artists and children”, hence they were universally admired.

 

Coin set of Free Irish State; woodcock (farthing), pig and piglets (halfpenny), hen and chicks (penny), hare (threepence), wolfhound (sixpence), bull (shilling), salmon (florin) and horse (half crown). Collectively known as the Barnyard Collection

During his time at the Royal Mint, with the reputation he gained from the Free Irish State coinage and the support from Sir Robert Johnson, Percy Metcalfe produced many models for various countries. Some of these are; Mihai the 1st of Romania, Boris the 3rd of Bulgaria, Faisal and Ghazi of Iraq, Fuad and Farouq of Egypt, Demeter and Poseidon portraits on the Greek coins of 1930.
