2018-P Roosevelt Dime
Struck on a Steel Planchet
98% Iron / 1.5 Grams
PCGS MS 60
This is a fascinating new discovery. United States Roosevelt Dime off-metals are very rare. There are only a few known on copper or foreign aluminum planchets.
This 2018 Roosevelt Dime was struck on a full-size steel planchet weighing 1.5 grams. It is “as struck”, with blazing luster and no surface marks or distractions, and a weak strike due to the hardness of the steel planchet.
Major United States Mint errors dated 2010 through 2022 are very scarce. It is a rare event to discover a U.S. off-metal, die cap, or double-struck major mint error dated 2010 or later.
The only official U.S. coin struck in steel was the 1943 Lincoln Cent during World War II. To have a 2018 Roosevelt Dime off-metal struck on a steel (98% iron) planchet is a very exciting discovery and an extremely rare mint error.
