I cannot find this easily seen RPM listed. It looks like a small strong D/a large weak D! What do you guys think?
I can't find one either. Could it be the head of the punch that surrounds the D that slightly incused the die as the punch was administered?
Ejection doubling and machine doubling are the same but why is my coin machine doubled and not an RPM?
Just a thought here. Not any claim to be an expert opinion. That said, the 1932 Washington Quarter has basically melt value in lower grade condition. Is it possible someone took a '32 no mint mark and struck their own D mm to give it rarity value?
ANSWER: This is an extreme case of ejection doubling. The characteristic is common on 1932-D 25c coins. I first learned of "Ejection Doubling" from Mint technicians when one expert authenticator at the time was gathering up these genuine coins from dealers for the OIN counterfeit collection. He thought they were added mintmarks. Most examples are not this spread. The action of shifting the metal often leaves a "seam-like" cut at the base of on side of the mintmark that makes it look to be unattached to the coins surface. Thus, it looks to be added and fooled many folks. in the 1970's.
