paralyse Bedrock of the Community United States 12057 Posts	Posted 06/18/2018 10:42 pm A bit more certain on this one but would appreciate confirmation or clarification! This AE ant of Probus caught my eye with the neat shield/spear obverse; the reverse has the emperor riding left on a horse, holding a scepter and facing a bound captive. It's a bit beat-up but has a nice patina in hand. The closest match I can find is similar to RIC V.2 157, a Rome minted 4th emission issue, officina 6 (279 AD?) assuming it's digamma. Mint in exergue appears to be R (crescent) digamma? Obverse is IMP PROBVS AVG (with a weird strike-through sort of error on the A in AVG?) Reverse is ADVENTVS AVG Thoughts appreciated as always.

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 06/18/2018 11:18 pm Congratulations for the Gordian 111 sestertius ! Not so happy with this one. Surface texture, mushy details and the lack of radial edge splits makes me suspicious about this one. Cast fake comes to mind. Style OK. Same appearance perhaps could come about with soft copper brush cleaning after recovery from direct soil contact burial, then artificial patination, and treatment with Renwax, but my 'gut' feeling tends towards the first explanation. Museums occasionally use Renwax to preserve genuine ancient copper or bronze coins, if the particular needs of a coin suggest it. Report this Post to the Staff
paralyse Bedrock of the Community United States 12057 Posts	Posted 06/19/2018 12:56 am Edge looks normal in hand, weight seems to be in range. It is mushy, but then again, it wasn't exactly expensive either :P There is some sign of corrosion or porosity.

paralyse Bedrock of the Community United States 12057 Posts	Posted 06/19/2018 10:15 am I am thinking about an olive oil dunk for a couple of months to see if some of the remaining crud will fall off.

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 06/20/2018 08:19 am Just remember that olive oil is slightly acidic, and has the potential to darken the appearance even further. Report this Post to the Staff

I'm loath to try acetone or mineral spirits on it, even though it's not a rare or valuable coin; I don't think distilled water would be effective.
