Can any of you fine ladies and gents provide any input (guesses or otherwise) as to what’s going on below the owl’s belly? To a neophyte like me it looks like a layer of spray paint… obv isn’t but. Thanks all and happpppy Friday!
Corrosion. If you see a paint like substance, it will not be the first time the surface of a coin has been altered by a colored substance - including paint!
I cannot tell much untoward, looks like hornsilver was removed and that was what was left. Extremely common with ancient silver coins. I would have to see the coin in hand or better pic to say anything else.
