<p>[QUOTE="kevin McGonigal, post: 8114951, member: 72790"]If you possibly can figure out specific gravity, do a specific gravity test on it. A coin that large should be doable with a minimum of equipment and a good likelihood of accuracy. You can find some good info, including videos on how to do it, on the Net. It looks good but that weight discrepancy needs to be explained. The weight is way off. I have in my collection a number of plated coins, including one which is an obviously plated Ptolemaic tetra with silver having flaked off in several places. Such coins were made in that place and time. I have no problems having several in my collection. They were part and parcel of Ancient coinage as counterfeiting was invented the day after coinage.[/QUOTE]</p><p><br /></p>
