We were approached in the 1990's to produce some replica medals as won by some of our clients we asked for some samples and this was one of them a gold/gilt over base metal replica Olympic medal Athena the Greek God appeared on coins that Alexander the Great  issued during his own lifetime, and the pair continued to be associated long after his death. This replica is based on A particularly fine gold medal in the Fitzwilliam museum,  probably dating from 242 CE, shows the helmeted head of the goddess on one side, and Alexander riding his horse Bucephalus in a lion hunt on the reverse. It seems to be historically accepted that this “Gold” medal was from the Olympic games AD 242 its not completely Flat possible shape of original? It is on a  22" chain 

How do we value this? Its really worth what someone is prepared to pay for it but having seem similar examples of other medal we think we have priced it correctly it is  3.3 cm high and 3 cm wide and weighs13 grams with the chain we have 2 other different medals available on ebay and will do a deal for the 3 if anyone is interested
