Verdi-care is a coin conservation and protective fluid. In my opinion, it's best used on coins exactly like this one, with green crust, and a dried out appearance. I very gently removed as much crust as I could with a toothpick, soaked the coin overnight, then used a cloth to blot/wipe the surface. This coin had already been wiped/cleaned in the past, so it will always be a problem coin, but I think it looks much better. Here are my before and after pics... enjoy.
As this is for educational purposes, this can be used on copper coins, what about silver ? Or is it to be used only for copper ?
The age old question rears its head yet once more I guess. Restoration good. Cleaning bad. Makes my head hurt.
What I like is the change in the dried out appearance. I have some coins with that look and it isn’t pleasing. I may invest in some of this.
It is specifically designed for copper coins. One of our member chemists, @BadThad invented it. I've never used it myself, but I've heard good things about it.
Haha, I have no opposition to trying it if I needed it. I'm perfectly in favor of properly conserving coins, and I believe judicious use of this chemical falls in that category. I haven't tried it because I don't buy the sorts of coins that would need it.
Point well-taken, but the appearance of dull, lifeless coins can be enhanced along with the promise of future protection.
I have a friend who found a 1/2 of a lg cent on his property on the Maryland eastern shore. He was very pleased to find it especially on his property. It was very dull pouris I treated it twice as the copper just sucked the product in....now still dull but it did improve the specimen 100 times better as some text now could be read....and the surface didn't seem as dry,or brittle. A small bottle last a long time as very little product is required to get the effects wanted. @BadThad thanks buddy great product.
Thad can speak for himself as to what he had in mind when he came up with the formula for this stuff. But, the simple fact is this - it's purpose is to remove verdigris. And it doesn't matter what kind of coin the verdigris is on. Verdigris is found on copper, silver, and gold coins, and sometimes even nickels, and Verdi-Care will remove verdigris from all of them. Granted, verdigris is found on copper coins more often than silver or gold coins. But it's still pretty common on both silver and gold. Less so on nickels.
