This thread would be better posted on the ancients part of CT but if you do send it there I would suspect someone would suggest that it is a fake. Such a coin can not be authenticated by poor photos (or good ones) but the obverse die is familiar: http://www.acsearch.info/search.html?id=758775 The reverse grade would lessen the value, if genuine, by half compared to the one above. The reverse photo color looks silver but that can be explained by poor photo practices. The reverse details and style do not look like aureus level either so the coin is one that would need to be shown to a high level expert.
