These are two different coins: Double Die or Machine Doubling or? Double D and Doubling on the 2? Let me have your thoughts!
Machine doubling on the first one. You can tell by the flat "shelf-like" doubling. On the other one it's die deterioration. Very common on the 1982. I found more '82's with it than without.
Gotcha, Just to help me learn a bit more I have a question: Wouldnt machine doubling affect the vast majority of the coin instead of just "The United States of America?
This is a quote from the link beneath it about machine doubling (strike doubling): "Strike doubling can affect all lettering on one or both sides, or could be detected on only one letter or a small portion of a device. Proof coins often exhibit strike doubling due to the excessive force employed. Strike doubling can be evident on a coin with a true doubled die or true RPM." http://www.stellacoinnews.com/index...from-other-forms-of-doubling-strike-doubling/
