I just got this coin in mail does anyone heard of a dd on a proof coin can anyone confirm? Here are the photos
There are doubled dies both obverse and reverse for 1968 S proof half's. That being said I can't really make out anything from your pictures and a clear picture of the entire reverse of the coin would be helpful.
You will probably have to take the coin out of the 2 x 2 to get a good pic. The N in UNUM looks weird.
Exactly where do you think there is doubling on this coin? Your original photos are centered on the motto so I guess there but it really doesn't look like it to me based off the photos you have provided so far. I do see some MD present around the United States of America.
Did it just appear in your mailbox, or did you purchase it? Also, may I ask if your understand what a doubled die (or what you're calling "dd") is? Honest question.
I purchase, and yes I do know a little about dd I'm not a expert on it, in the top of the Eagles head on the word e pruritus unum shows the dd, the pictures are not that great but it is the best I can do.
