Wow thanks for all the helpful reactions. 😀
I'm going to tag the people who asked for edge pictures here @sand @ambr0zie @Deinomenid @zadie. Hopefully these are clear enough. I also added some better macro pictures of the faces.
I just weighed it with a cheap kitchen scale and it registered 16 grams, including the ring. The diameter is about 25-26 mm (bit difficult to see with a camera, but it's really 25 mm 😅). Both are more or less the same as is written here https://www.cngcoins.com/Coin.aspx?CoinID=99640.
Are Syracusan coins faked a lot? Or just Greek coins in general?
Thanks for all your guys' help 🙂
