Newly registered, but I found a 2000P-RPM Sacagawea as well. I've looked at it for MD (mech-doubling?) and it doesn't show anything as strong as the MM shows in regards to doubling. I'm only speculating, but with this being a, then new coin (planchet to final product), is it possible that the MM was punched separately due to unknown reasons? Like for example, if early on (1999 or so) they hadn't known that the Denver mint would be involved with production. Possibly having left the MM to be punched on the earlier dies for that reason. Or even possibly because because it wasn't Included originally out of low expectations of its reception. The low expectations due to the backlash from the 1979 $1 coin release, it's kind the quarter, and the debacle they incestuously birthed. (I guess I shouldn't be so critical of the
SBA, I was given .82¢ change which turned out to be $3.07 the other day)
The point is, it's got two confirmed, at least on my end, sightings. Is it something worth pursuing?
