I was really happy how this worked. I first soaked it in vinegar which made the verdigris thinner. Then I used Dellar's Darkener to make it darker to hide the verdigris even more. I don't have any Verdi-Gone so I couldn't just use that. There is still a spot on his(/her???) head by the L in LIBERTY. It doesn't really bother me as the rest of the coin looks so much better. Not really sure how it happened but the after pictures are first. Grades?
It is an princess wearing a feathered headband...So that should answer your question about gender. Now for the coin, itself, I'm amazed, you cleaned a coin good! I tell ya! See what NGC does to it...lol Very nice!
I'd like to see a 'magnified and highlighted' pic of the verdigris area to see if there is "pitting" showing in that area?
Hummm....looks are deceiving, lol. The verdigris is still there, it's just absorbed some of the sulfur in the darkener. I'll say it once again, if you guys use vinegar you're feeding the verdigris (copper acetate). Vinegar contains acetic acid, which is responsible for the temporary chemical reaction with the verdigris. However, it also supplies more food for the verdigris (acetate radicals).
Verdi-gone would have done a much better job without damaging the rest of the coin. It looks like a lightly dipped coin to me. I think it has more problems now but it looks cleaner.
I agree with you. The thing is, vinegar costs $2 and Verdi-Gone is a bit pricey. I would usually just not buy a coin with damage like this, but I got it for a dollar and it is in VF so I wanted to experiment.
I agree it looks better than it did before, but you can still see the corrosion and damage. I have not tried anything like this.
Well I'm not buying any more coins like this so it would be a waste now. I believe it is a good product at a decent price, but I don't need it.
I am glad you have come to this realization. I truly believe it will benefit you (and the rest of numismatics)....Mike
I really don't think this coin has been helped. Sure it looks better, but as you said, you used darkener to hide the rest of hte verdigris. Hiding verdigris isn't the main goal when your attempting to "clean" a coin. Getting rid of it is the goal. The way I look at it is if I can get rid of the verdigris and be left with a but ugly coin, I am still happy. Having it come out with an appealing look is just a bonus. I say you should tackle it again, but please, don't use vinegar.
