[QUOTE="robinjojo, post: 26792362, member: 110226"]I am not familiar with the coinage of Gortyna, but I can speak generally about the edge splits. I think they are due to the pressure of the hammer strike. These coins, like other ancients, did not have collar dies to absorb the pressure waves, which emanated from the center of the flan outwards. This pressure can cause the metal to rupture or split, especially in spots where there are slight differences in the mixture of silver with the alloy metal, which is almost always copper. The splits on your coin are relatively small. I have seen other splits that actually extend from the edge towards the middle of the flan. As for jewelry use, I would look for signs of solder or mount marks. I don't see the indents or anything particularly unusual. These flans were cast, so any marks could be due to rounding off the casting features, such as the sprue at the mint. The weight is on the high side, but not to a degree that would raise a caution flag for me. That's a very nice coin![/QUOTE]
