2001-P Sacagawea Dollar--Struck on a Nickel Planchet--MS-61 (NGC).5.0 grams. The strike is nearly flush with the upper right obverse and lower right reverse borders. The difference in size between the dollar dies and nickel planchet has resulted in the loss of only the top half of the letters in the words UNITED STATES OF on the reverse and a few minor details along the lower left obverse border. All features that are present are fully impressed and sharp, the surfaces bright with satiny mint brilliance. A thin, shallow obverse scuff over and behind Sacagaweas head is the only impediment to a higher Mint State grade. The companion piece to the Sacagawea dollar struck on a cent planchet that we are also offering in this sale, this wrong planchet error involving a nickel blank is nearly as rare, and equally as desirable.
