I Found A Weird Murcury Dime A Couple Days Ago It Had Black Patina With Really Shiny Spots On It?

p.s. sorry about the bad pic I thought it would come out better but you can see the patina and the shiny parts on it.

i have a merc I found last week with a similar hardened black something or other stuck to it.
I'm trying electrolysis right now to get it of. Some of it has come off and the shine of the silver is there. It's been about 40 minutes and have had to change the water a few times already. Now it seems to be slowing down and still most of the goop is there.

Good luck with yours though and tell us what you did.

Electrolysis + Silver = Quickest way to ruin it. Any other way ( excluding hard abrasives ) will clean it

if it is silver. Whatever you dont " zap " silver. You will just make it worse...

what other ways do you sugest becuase so far nothing else is getting the stuff off. some of the black stuff came off today though and it is a bit shinier than before

Sometimes the dark black can be sap....I have used WD40 with some success on similar dimes.....

cant you ruin coins when you clean them is it the same for this one?
