1951-P Possible New DDO ?

Is it retooling perhaps?

Your coin does not look to be a particularly late die stage, but it is an interesting bit. First, unlike the 1953 DDO-002 (I'm going to use all CONECA numbers here) which has doubling under the LIEBERTY that is easy to see with a loupe but hard to see under the scope, the 1951 DDO-002 is hard to see with a loupe but pretty clear under the scope. Also, the 1953 is fairly common, while the 1951 is not (possibly because of the difficulty in seeing it with a loupe).

But if you had 1951 DDO-002, you would certainly see doubling under the BE of LIBERTY in any stage. The bits around the chin are, as noted above, probably some re-tooling or similar action that went on and not true doubling. At least it doesn't look like doubling to me. You also put an arrow on the forehead doubling. I checked my 1951 DDO-002 and yes, it has that, but that type of doubling can be found on many coins from that era. Whether it is MD, an engraving issue, or true doubling I have never really figured out. But it can't be used, by itself, to identify any one die.

So likely if you can't see anything under LIBERTY, then the coin is interesting but probably not hub doubled. Anyway, some comments, nothing more, to help a bit in figuring it out.

Definitely retooling around the head, not a DDO. Without pictures of the doubling on LIBERTY, I am unconvinced.

I have the 1951 penny as well...was told it was DDO with other errors, will u look at it for me?

thank you guys
