hi just got this back from a cleaner to get rid of silver horn crust any way to tone it down from a new member Clodius Albinus IMP CAE D CLO SEP ALB AVG Ar. denarius 195-197; Lugdunum
That really depends on whether the cleaner applied anything to keep it from toning. If not, time is your friend and it will naturally tone in a few years. Certainly you can expose the coin to Sulphur fumes or even just place it in a sunny window with some oak, cheap paper or good old factory air if you live in the right place. Heat speeds things up but baking it in a hot oven is not a certain outcome. In any event, there is no guarantee that all parts of the surface will retone at the same rate so you might end up with something as blotchy as when you started. Were the coin mine, I'd watch it for a few years before doing anything rash. It is a very nice coin. Mine is a different reverse (GEN LVG COS II) with a die damaged by a serious clash.
Very nice work!!! --Yeah, if I had an Albinus, I'd pay someone else to clean it. And the coin! Replete with the martial motif, underscoring the context. WOoow.
