This does look interesting. Can you post images of the full obverse and reverse of the coin?
The experts should be along shortly to help you out!

Hmmm, I'm not finding anything matching this coin online.
Could be an unlisted variety or possibly MD. Not too sure but it definitely looks like there could be something there.

Very interesting but it is MD. #1 rule is, Doubling INCREASES the size of a normal letter(number). This indeed has a "soft" rounded look like some DDO / DDR but it is still normal size for a letter. MD is caused in the strike by movement of the die upon striking OR retraction, a stutter so to speak, mechanically or "hop" might better describe, this being very slight. Nice eyes tho, you'll really know when you see a real one!   Maybe these will help!   Try this example:  Edited by Crazyb0

So looking at another posting about doubling in regards to doubling of E Pluribus Unum, http://goccf.com/t/292010 it was pointed out that true doubling in this region of the coin would generate doubling or oblongness of the dots between the words and in this example the machine doubled coin had dots that looked completely round and normal. When looking at the pictures of mine I'm definitely seeing that the dots are not perfectly round and there is a line going through them. Also when looking very closely there appears to be notching at the top right of the N and very hard to make out but at the bottom right of the R and the bottom left corner of the I. Any thoughts on this? I realize there are no known examples of this type of doubling for this year and mint mark however, due to the looks of this coin and what appears to be doubling on the dots as well, I would like to be certain. MDD coins I've come across so far in my short amount of time coin roll hunting look to have letters and numbers that appear much skinnier on the rounded edge portion and pressed down/flat at the shelved base. Here's a good example I found. Additional thoughts on all of this?  Edited by Crhnewbie

crhnewbie. Here's what I see...this is a result of two factors. First it is a 'shaving" MD (YELLOW direction, RED location) and possibly an overpolished die. the polishing of the fields got close to the digits filling with the diamond polish making them thinner and also at the bottom of device channel (remember reversed image on die)making an "indention" on device "top" Since devices are normal sized or reduced this CANNOT be a doubling effect...this is a STRIKE error NOT a Hubbing error. Two different processes and TIMES the errors are introduced. Doubling is when Die are Made, not used. Turn your Email on in your profile. You cant contact us, but we can you. |

Crazybo, were you referencing the last picture I sent over of the 1981 penny? I know that was MDD as I was using it as a reference of what I believe MDD looks like. Just wondering as you mentioned red and yellow and that's the only picture I've posted here that appears to have those colors and you used the term "digits" instead of letters further making me believe that's what you were referencing. This is the last I'll post however, this picture best shows what looked to me like notching at the bottom left of each letter as well as top right of the N.  Edited by Crhnewbie

here's the "Analysis"! lol! Marked up last pic w/ all notes. Your notches are pieces missing of those normal letters. I'll use term device which means letters and digits(numbers). I do see a curving downward rounding on left sides of letters, this is die wear and filling up with polishing debris. What I've indicated as filled, may just be PMD, hard to be sure, at that mag, everything begins to appear...weird. True doubling can be reckoned w/30x or less about 99% of the time.
