Before I begin, want to write a disclaimer that I love the product VerdiCare
and have had successful results using it before: http://goccf.com/t/319050&SearchTerms=Verdicare
In my album I had a nicely toned Wheat cent
& it was was developing a carbon spot (or?) rather rapidly. There was an existing spot under the R in America on the reverse, wasnt really distracting at the time. The larger & newer spot was developing rapidly under the O in one.
I was aware that VerdiCare
does not remove carbon spots, but I wanted to conserve the coin against any further environmental damage anyway.
I soaked the coin with a few drops over night, and when I went to remove & dry the next day I noticed the toning was gone & color of the coin completely changed to a greenish color.
My question is, was the color artificial, or was this coin exhibiting some sort of advanced Environmental damage under the toning that caused this damage? The color progression and cartwheel luster led me to believe it was genuinely toned, but the spotting on the reverse makes me think something else was going on..I dont think VerdiCare
was the culprit as I have had many other coins successfully conserved, including toned coins. I'd also note I have many other toned coins in this same album for years that have not had any ED develop as this one did in under a year it's been in the album.
