Some known error varieties associated with the James K. Polk Presidential Dollar coin (issued in 2009) include:
- Missing Edge Lettering: This occurs when the edge lettering, which includes the date, mint mark, and motto “In God We Trust,” is absent from the coin. These are also known as “godless dollars.”
- Doubled Edge Lettering: This happens when the edge lettering is applied twice, resulting in a doubled appearance. This can occur as:
– Overlapped Errors: Doubled edge lettering running in the same direction.
– Inverted Errors: Doubled edge lettering running in opposite directions and upside down.
- Extra Number on Rim: A rare error where an extra digit appears on the coin’s rim.
- Die Adjustment Strike: In these instances, the design may appear faded, potentially with missing details like the President’s name or the motto.
- Die Chips & Cracks: These can appear as small pieces of metal chipped off or cracks on the coin’s surface, such as a filled “S” on the reverse.
- Die Scraped: This error results in scratches or marks on the coin’s surface due to a scraped die.
- Slipped Edge Lettering: This occurs when a portion of the edge lettering appears to have “slipped” during the minting process, causing it to be misplaced or misaligned.
Collectors are particularly interested in these error coins, with some fetching significant prices depending on their condition and the severity of the error.

Thanks for asking. The rare 1984 $1 coin was struck on a 10-cent blank in error, instead of a $1 blank, meaning the coin is silver rather than gold. One of the coins went to auction with a price guide of between $2,000 and $3,000 this week, sold by auctioneers Roxbury’s Auction House.
