(1943) Denver Quarter Struck on U.S. Steel Cent Planchet
There are only a few known Washington Quarters struck on U.S. Steel Cent Planchets. This is the only one that Iím aware of from the Denver Mint.
NCS conserved this coin and described it as corroded. It now has a bright shiny reprocessed look and has all of the details of an uncirculated coin. Extremely rare and missing from almost every major mint error collection.
