Quite easily as a matter of fact. Just because a coin is unc doesn't mean that it can't get moisture droplets on it from any number of sources.
Ahh, well then. I guess we'll just have to let you see an older one :) [ATTACH] [ATTACH] [ATTACH]
No Thad I didn't contradict myself at all. Yes, when rinsed some water does stick to the surface of the coin. But when you rinse a coin in acetone...
Ya might want to look into getting new glasses Ray :D
Nor do I think it is "necessary". But I do think it is a good idea. And it does, it prevents those few cases where the coin develops a whitish...

Ahhhhh - so you're the guy who's been doctoring all those old cents [ATTACH] And yeah, the devil made me say that :D Now then, go do that same...
I don't disagree, they are both in the same category - in that regard. However, there is a distinct and I think a very important difference...
Yeah, I would, to a limited extent and only under certain conditions. Verdigris by its very nature is capable of absorbing moisture, whereas the...
The mint has made a point of making sure that their Proof coins are cameo since 1973. It was only prior to that date that they didn't care. Before...
