The logo of the centre is a silver drachm in the Royal Coin Collection of the Danish National Museum (Sylloge Nummorum Graecorum 4, Paphlagonia, pl. 8.278). It was minted in the 4th century BC in the city of Sinope, and it is showing a sea eagle on the back of a dolphin. Beneath is the abbreviated name of the city SINO(pe), and above the eagle is an inscription with part of the name of the moneyer magistrate, AGR. Beneath the tail of the eagle is the shadow of a similar inscription.
This depiction was used not only on the coins of Sinope, but also on amphorae stamped in the same city, as well as for coins of Histria and Olbia. It has been suggested that the coin type marks a contemporary alliance of the mentioned cities.
