Well, definitely no rubs on this coin. I'm a bit confused by the AU guesses, but I have the advantage of seeing the coin in hand. Very good...
Keep the guesses coming! I'll reveal the grade Monday evening when I get home from work.
So how do you know its a fake? Educate us.
It is not a double strike, it is a doubled die. I'm not sure if this is considered the obverse or reverse of this coin. Doubled dies on foreign...
Have you seen the coins in the National Numismatic Collection of the Smithsonian? The goals of collectors have changed over the last couple of...
Or it could be due to a weak strike.... The 1921 Peace dollar is infamous for its awful strike. Look at the luster in the 3rd picture of post #12...
Isn't there a museum at the old mint building? Has anyone been?
They are all dated 1976, but yes, the mint started making them in 1975.
What White shows is that if you weigh a coin before and after dipping, there will be a difference. And what rmpsrpms is trying to tell you above...

No, it is actually the exact opposite of that. Metals naturally gain a patina, which is a surface oxide or sulfide layer. This passive layer slows...
What you've described is "conservation," not "cleaning" of any sort. There is a difference. Conservation's goal is to stabilize and preserve the...

I saw this in a seller's inventory, and I knew I had to make it mine. This is the most colorfully toned example of this coin I've ever seen. It's...
I'd wager 63RB, but something about the look of the reverse fields makes me think it might be AU-58.
Dealers will often buy large amounts of mint sets and try to cherry the high grade ones. What's left over are dozens of cut-up mint sets like...
I can agree to that :)
Some cool coins here, everyone!
Let me just clarify: acetone is not a dip. "Dips" have a non-neutral pH and will affect the metal of the coin; acetone only affects organic things...
