I have spotted this one and have tracked it down to being similar to S12413, RIC 474 on Wildwinds, but the altar design is very different. Is it just a fake/replica or a lesser known variety? I do not have it in hand so I cannot confirm weight or dimensions.
Thanks for that - I suspected as much but wanted to be sure I wasn't missing a potential bargain. It is in a non-coin general auction labelled just as "Unidentified Roman Coin" with a very low estimate, so definitely a "caveat emptor" situation.
Sadly yes, but not a specialist coin auction. Described loosely as "Unidentified Roman Coin" and with an estimate of £10 to £20. I guess if several people with more money than sense convinced themselves it might be genuine, caveat emptor applies.
