Tetradrachm (four drachma) coin with the head of Arethusa, the patron nymph of Syracuse. Country of Origin: Italy. Period/ Date: 405 - 400 BC. Place of Origin: Syracuse. Material: Silver.I am impressed by the degree of relief on the coin. The edges almost look like the coin has been milled, but that technology didn't happen until the modern era, so those must be some kind of stress cracks from the stamping.
