This coin should come after RIC VII London 25, which is the same except that coin ends with AVG while this one ends with AG...see RIC 28, a SOLI coin with same obverse legend. Not listed in Cloke & Toone either.

MARTI CONSERVATORI; Mars helmeted, in military dress, stdg. r. looking l., holding reversed spear, hand resting on shield; across fields S-F.

And not sold! Well, this green coin isn't beautiful but $60 (for two coins) was a rather moderate price.

So congratulations! I follow CNG auctions on Sixbid and there is still "Result: unverkauft".

I cleaned most of the verdigris off. I also found out it that it was discovered in Wendover UK.

Victor - what technique do you use to remove verdigris? I had purchased a London mint Constantius I "P FEL" follis from you a while back and had always wanted to clean it up as I feel it has a ton of potential under all that green

I soak in 10% ammonia with frequent rinses and scrubbings. With bronze, you always run the risk of revealing porous surfaces, so be careful. The ammonia turns blue as the verdigris is removed. I would urge caution with your Constantius coin as it's surfaces are different than this coin I just cleaned.
