Tetradrachm - Kolotes

Apollonia Pontika — modern Sozopol on the Bulgarian Black Sea coast — was a Milesian colony whose silver coinage served the grain and timber trade routes running between the Pontic hinterland and the Aegean world. The anchor type to which this tetradrachm belongs was the city's primary trading identity for roughly a century, and the kolotes — the freshwater crayfish on the reverse — appears to reference local fauna rather than carry mythological weight.

Dies within the SNG BM 154–160 range show measurable variation in the crayfish rendering, suggesting multiple engravers working across the emission.
