The top NGC-certified lot is a 1999-P New Jersey State Quarter graded NGC MS 65 (lot 91146) that was struck on a foreign planchet. In addition to being the wrong composition, the planchet used was much too small, cutting off much of the text near the edges. More than a week before the auction, bidding had already passed $6,000.

A second highlight is a 2000-P $1 Sacagawea Dollar Struck 50% Off Center graded NGC MS 66 (lot 91199). The off-center strike resulted in the absence of the design elements above Sacagawea’s forehead on the obverse and below the eagle’s body on the reverse. More than a week before the auction, bidding had already passed $2,000.
