My 2011 Silver Proof Set has this coin in it. I would say its MD, but thought I would let someone with more experience have a look at it. Thanks in advance.
I can't tell from the pictures of the doubled image is flat or rounded, but my guess would be MD...interesting to find it on a Proof set! If you don't like it, I'll trade you a non-MD set for it.
I thought it was pretty neat as well. I think its MD to ,but i'm not an expert. I think I'll hold on to it,but thanks for the offer. Wondering if it will carry a premium?
I'm not an expert, either. I believe MDs are created by too much pressure and/or a loose die. I've seen quite a few MDs on business strike coins, but I don't recall ever seeing one on a proof coin. I always thought proof coins were struck twice, so I'm not sure what MD would look like under those conditions. I would hang on to it if I were you.
I just got my February 21st edition of Coin World and on page #74, there's an interesting article on "Lazer Doubling". They don't call it that, but it gives the "appearance" of doubling so I call it that. Once the die is polished, a laser is then used to make the pock-marked finish that is the new proof "frosting". They show a 2007 Adams Prez proof dollar that was made from a die prepared with a misaligned laser. The pock-marks are shifted to the right, creating a doubled appearance. As near as I can tell from the pictures, the OPs coin appears to be "machine doubled" (MD) v.s. "Laser Doubled" (LD) so the article likely doesn't apply...but I thought it was interesting enough to share. Back to machine doubling...here's a question I had that I hope someone can answer... I've looked at quite a few coins, both business strike and proof. I've seen many MD business strike coins, but I don't ever recall seeing a MD proof coin. Has anyone else ever seen one? ...other than the OPs coin, that is. Thanks! :bow:
Machine Doubling on Proof coins is not uncommon since proof coins do get struck at least twice anyway. There are many Eisenhower Proof Dollars that have machine doubling. There are even SMS coins that have machine doubling. No premium should be assumed unless its sold to someone who just does not know any better.
Seems reasonable it would happen to proofs, also...I just hadn't seen one until now. Thought there might be a chance they were more careful with the proofs. Thanks!
Here are some pics I just scraped up. First a 1967 SMS Kennedy: A different SMS Kennedy (This one actually looks pretty cool!): A 1971-S IKE Dollar: How about a 2008-S Silver Kennedy:
