2001-P Sacagawea Dollar--Struck 20% off Center--MS-65 (NGC). Highly lustrous and mostly brilliant with just the faintest accents of toning. Struck considerably off center, but fortunately with the central devices complete and a full date. In fact, the piece could not have been struck much farther off and still maintained these elements. A 2000-P dated example is ranked as coin #77 in the book <em>100 Greatest U.S. Error Coins</em>. The piece plated is a little farther off center, but in the opinion of your cataloger (JP), this piece is actually more desirable due to the completeness of the design being well balanced against the shift of the centering. Off center Sacagawea dollars are much rarer than Anthony dollars, even when compared solely to those issued in 1999. New coining presses used for these dollars virtually eliminated such errors after an initial spate of wild errors was halted. In 2010, after nearly a decade had passed since the first issue of the Sacagawea dollar, it was estimated by the authors of the <em>100 Greatest</em> book that just five or six off center Sacagawea dollars were known. The more recent Presidential dollars are even rarer with such errors. In fact, collecting silver dollar errors of any kind presents quite the challenge, and it would be a really neat endeavor to try for an error of each type. Such a collection would require years of enjoyable hunting.
