And that's exactly the problem with 1 word (that same word) for 2 different things. The misuse of that 1 word confuses people. There is cleaning,...
Some guys don't mark their coins with a grade because they know whatever they mark it, somebody will disagree. And often enough that disagreement...
No Dave, I didn't say that at all. I said that "certain plastics", meaning specific kinds of plastics, give off harmful gasses. The other kinds of...
I think it might be a good idea to rinse that coin in some acetone, looks like what might be some PVC residue on it.
Yes, certain plastics can be problematic when in proximity to coins. That's because the plastics give off gasses and it is the gasses that are...
Then it gets really noisy ! A lot !!
Welllllll, that depends on how late it is :D
Good thing ya told us Tom. We never woulda known from lookin at your avatar :D

Savy - I think there is something else you should consider, there is toning, and then there is toning. Toning can vary greatly, in it's early...
A final thought Matt. You mentioned that you use acetone to remove the oils after treatment. But to my eye the coins in the pics still have what I...
Definitely not always, but yeah, they often do. But nowhere near as often as they used to, and nowhere near to the degree (amount) that they used...
Yeah sure, it could be done. But I've never actually seen one that was. I'm pretty sure the reason it is not is because the time factor is much...
Good demo, but it looks like the PVC had already done its damage.
It happens often enough. PCGS has more lenient standards than NGC for every special designation there is.
In all fairness, those kind of mistakes are not made by the people identifying and grading the coins. In other words the professional graders have...
Not really. Most books only cover the subject in general, for all coins, not for any specific series or type. Counterfeit Gold Coins by Alfred...
This one always took the cake IMO - [ATTACH]
