Re: DON"T USE NCS !!!!

at this point, there's not a whole lot you can do. chalk it up as a learning experience and move on.
just remember, a true coin collector, want's the patina and nicks, it gives the coin character

Re: DON"T USE NCS !!!!

I don't clean coins I find anymore except with olive oil, BUT, I have found a lot of pitted coins, acidic soils I guess. Except for the color I have done that damage to some. You know you can have a coin you can recognize and by the time you clean it up all the blistering and corrosion on it have disappeared and you can have a nice, shiny copper slug. Best not to play with em, but I have been tempted at times to have 'em cleaned. So you, sir, have taught me that I can do that well myself.

Re: DON"T USE NCS !!!!

Most "pros" would have enough knowledge to NEUTRALIZE the verdigris and not remove it !! So they are far from professionals!! If they had a idea that was going to happen they should have notified me by phone email or letter.. They had all that info.. I couldn't stand to look at it anymore (made me sick!) so it's on feebay now..

Not being a coin collector, I don't know which version would be given more value. But the damage to the coin (very pitted) appears to have been done by the corrosion, not by the cleaning.

The cleaned version does show much more detail, especially in the shield, the feathers, and the wheat.

It wasn´t done by corrosion!
The coins has had a nice green malachit paitna and all features was turned into this patina!
With removing it, you got what you see there - features are gone and only a thin ugly cuprit layer is remaining.
To use ANY kind of chemicals on such a patination is NOT professional !

I real missing the times, when people who did this gets cut off their hands !
