There are only two known off-metals in the Presidential Dollar series. Recently PCGS authenticated and certified this Washington Dollar struck on a U.S. Nickel planchet. It graded Mint State 66 and is a visually stunning and dramatic mint error.

The other off-metal Presidential dollar is a John Quincy Adams struck on a U.S. Nickel planchet. It was also authenticated and certified by PCGS as a Mint State 67.

Considering that four years have passed (2007, 2008, 2009 & 2010) and millions of each Presidential Dollar have been struck, it is amazing that these two are the only off-metals reported.
