Why Did Kyzikos Place a Fish on 270 Different Coins?

In the ancient numismatic world, some cities immortalized themselves with a single powerful symbol: such as Athens' owl, Aegina's tortoise, and Ephesus' bee. Yet, no city combined this brand identity with such consistency and artistic variety as Kyzikos in the region of Mysia.

For hundreds of years, starting from the 6th century BCE, on every electrum coin issued from the mint of Kyzikos, there was one unchanging signature, no matter how much the main design varied: a small figure of a tuna. So, what was the secret behind the insistence on placing this humble fish on one of the ancient world's most important commercial currencies, and what does this tell us about the city's identity?

The answer to this question lies in Kyzikos' geography and economy. Strategically located on the coast of the Propontis (Sea of Marmara), the city was situated on the migratory path of massive tuna schools that traveled between the Black Sea and the Aegean each year. This natural abundance made Kyzikos one of the ancient world's largest centers for fishing and fish processing. The city accumulated immense wealth through tuna fishing, salting, and the production of garum (fermented fish sauce).3 Tuna was not merely a food source for Kyzikos, but also the cornerstone of its economic power and prosperity.

Therefore, when they began minting their own coins around 600 BCE, it was entirely logical for them to choose this symbol, which formed the economic DNA of their city. The tuna figure was like a "Made in Kyzikos" stamp struck on the coin. This was an instantly recognizable brand identity, indicating that the coin's weight and purity were guaranteed by Kyzikos' economic power. These electrum staters, known as "Kyzikenes," gained such widespread acceptance in international trade, alongside Persian darics, that they can be considered the ancient world's first "dollar" or "euro." When a merchant presented a Kyzikene stater in any port from Athens to Egypt, everyone was assured of the coin's value and origin thanks to the tuna emblem on it.

However, Kyzikos' numismatic genius lay not only in this consistent branding but also in the incredible artistic variety it created around this brand. While the simple square punch on the reverse (quadripartite incuse square) remained constant, the main design on the obverse changed almost every year. To date, over 270 different obverse designs have been recorded, and this number continues to grow with each new discovery. These designs are virtually an encyclopedia of Greek mythology and art.

What was not present in this rich repertoire? Gods and heroes like Zeus, Apollo, Heracles; mythological creatures such as griffins, sphinxes, pegasi; powerful animals like lions, bulls, eagles, and even sea monsters like Skylla... Each design was a miniature work of art, crafted by the most skilled die engravers of the era. However, in each of these designs, whether as part of the main figure or as a small emblem below, the famous tuna fish was invariably present. This strategy provided Kyzikos with two significant advantages. Firstly, the constantly changing designs made counterfeiting the currency difficult. Secondly, this artistic variety transformed Kyzikene staters from mere currency into objects of aesthetic desire.

In conclusion, Kyzikos' coins offer a lesson in how to create a successful brand in the ancient world. They took a symbol that formed the economic foundation of their city (the tuna) and made it an unvarying guarantee of their currency. Then, by combining this fixed and reliable brand with constantly changing, artistically striking designs, they maximized both commercial trustworthiness and aesthetic appeal. Each coin from Kyzikos reminds us: A fish is not just a fish; when told correctly, it can be a symbol of an empire's wealth and artistic spirit.
