Die
Doubled die
The die itself received a misaligned second impression during manufacture, so every coin struck from it carries the same doubling.
How to spot it
Look for clear separation and rounded edges on the date, lettering or motto. True doubling is raised and shows a full second image, not a flat smear.
Value impact
The strongest doubled dies are the most valuable U.S. error class, with premiums from a few dollars to five figures.
