With a curly haired man on one side and a standing eagle on the other, there is a good chance that requester Chris has a silver tetradrachm from the ancient Ptolemaic Kingdom. There are certainly other possibilities, and these patterns were used on other denomination coinage, but silver tetradrachms are the most popular and highly sought collectible. Silver tetradrachms weigh about 13.5 grams (plus/minus 1 gram) and have a diameter of about 26.5 mm (plus/minus 2 mm).
The Ptolemaic Kingdom was a Hellenistic kingdom based in Egypt ruled by the Ptolemaic dynasty which started with Ptolemy I after the death of Alexander the Great (323BC) and ended with Roman conquest in 30BC. Generally coins of the early Ptolemys are worth somewhat more than coins of later Ptolemys.
The inscriptions are important. Transliterating from Greek, they read PTOLEMAIOY BASILEUS, or KING PTOLEMY.
