In 2016 two gold coins were found between the towns of Balchik and Kavarna where the capital of the Second Scythian kingdom, was probably located. One of the coin is a quarter stater of Olbia, minted under the Athenian coin system in the period 310 - 300 BC. It is descripted by the Russian numismatists Karishkovskiy and Anokhin as a hemidrahm or triobol. On the obverse is depicted the goddess Demetra with a wreath of stalks grains, turned left. The reverse presents a dolphin to the left, below it a monogram ОΛ. The coins has a diameter of 11 mm and a weight 2,157 g.
The other coin is also quarter stater with weight 2,103 g and a diameter 12 mm. On the obverse is depicted the head of god Apollo with a laured wreath, turned left. Above the image there is a monogram ΔI. On the reverse is a Scythian with a spear in the right hand on a horse in gallop turned to the left. From the studies and comparisons
made, it can be assumed that this is a quarter stater of the king of Bosporan kingdom, Perissad IV, minted in Panticapaion during the period 140 - 130 BC.
