1986 U.S. $1 Silver Eagle
Reverse Struck on Emery Disc
Certified by PCGS
SOLD

This is a spectacular One Dollar Silver Eagle struck at the Philadelphia Mint in 1986. A 3M sanding disk adhered to the die and was struck into the reverse of a blank planchet.

There are five or six U.S. Silver Eagles known to exist with either the obverse or reverse 100% struck through a 3M sanding disk.

The strike on the sanding disk is incredibly sharp and has a surprising amount of detail considering that it is not metal. This dramatic piece is one of the most unusual major mint errors ever discovered.


Here is a letter from the Department of the Treasury relating to the discovery of a new type of mint error. In 1986 several Silver American Eagle coins were struck on emery discs and a few others were struck through the emery disc. PCGS has certified two mated sets. This letter is in response to the discovery coin twenty years ago.
