Hello everyone!
Recently I received 3 Alexander III bronze coins, 2 half and 1 quarter.
The half with a horse came from a reputable dealer, so it should be good.
The half with the shield/helmet, and the quarter with the bow/quiver was from a dealer that I am not as sure about.
The coins all seem close enough to their weights and dimensions.
The half piece with shield/helmet concerns me a bit. If I rub it with the edge of my fingernail, it leaves a dark residue on my nail. Also it seems very pitted(from casting?). The edge of the coin doesn't have a casting line, but something seems "off" to me about the coin.
Sorry my camera is so bad, I have to learn how to take better pictures of coins.
Maybe these images wont be good enough.
