This one is NNW but it isn't supposed to exist correct at almost a decade later?

ejecton, doub, die bounce or deterioration i think

This is tricky stuff no doubt about it. That really looked like I found something. Thanks for being gentle.

i'm pretty sure someone here said that they now do the MM as part of the design, no separate punch, thus no MM since like 1992 or something? MintErrors

They did that's exactly why I was confused by the mintmark looking like a RPM.

Yes, it was in 1990 or 1991 that the Mint added the mint mark to the design (master die/hub) basically eliminating the RPM's and OMM's outright.

From that point on, IF a mint mark looks doubled, since it is part of the design, there are two strong possibilities. Its either a doubled die or, it's worthless doubling. For a doubled die, I would imagine more design elements should show some form of doubling as well.
