There's a very simple experiment that anybody can do themselves. Buy any .999 or .9999 gold coin you want. Leave it exposed to the air at home for...
I know Mike, but usually putty is applied in just the affected areas like a hit, hairline or scratch in very small quantities. On that coin they...
Teletrade and Heritage are your best bets.
If that's putty it would be the heaviest concentration I have ever seen on a coin, and in areas where I have never seen it. I doubt it could have...
Check the dealers listed here - http://www.cointalk.com/t14152/ - quite a few of them often have coins of the type you want. But you do have to...
Did you read the first link I provided ? It pretty much contradicts everything you're saying. "Amorphous AuxOy compounds have been produced...

I only live a few hours from there, why ? What do you need ?
Forget about the wire brush. Best guess is they use a chemical dip.
Same place it's been for the last 4 years ;) But don't feel bad, hardly anybody ever looks there. I suppose it's the name I gave it - Numismatic...
Well, when you are doing your research make sure to check out the refining method known as cupellation. It is one of the oldest. And oddly enough...
Hardly - it would in fact be much easier to mint pure gold. There were two reasons and only two reasons that the purity of the metal was ever...
Yes they do. I don't have any pictures to show you of very, very old ones. About 400 years old would be the oldest I had in my collection but they...
You are making an assumption. It's not that they can't do it, it's that they choose not to do it. Then you need to so some research because...
