Denomination : Silver stater.
Reference : Sear Greek - 1858
Size : 16.2 x 18.8 mm. Weight : 12.12 grams.
Grade : aVF, on an oval flan that fits the turtle well with at least parts of all four flippers and the head on the flan, , but part of the reverse punch is off.
Obverse : Sea turtle with a smooth shell. There is one small faint countermark on the turtle's back, but I have not yet identified what countermark it is.
Reverse : Incuse square with a "proto-skew" pattern. The pattern is partly off the flan.
