DC-100c-2009P-01 Die Chip

Description

Oriented as a Position B coin — where the edge lettering reads normally when the obverse faces up and the coin is rotated on its vertical axis — this 2009 Philadelphia Mint James K. Polk Presidential Dollar carries the first cataloged die chip for the date and position combination. Die chips form when a small fragment of the die surface breaks away, leaving a tiny cavity that fills with metal during striking to produce a raised blob on the finished coin. Presidential Dollars, minted from 2007 through 2016 honoring each U.S. president in order of service, feature incused edge lettering that creates two orientations designated Position A and Position B. Polk, the eleventh president who served from 1845 to 1849, is remembered for the annexation of Texas and the Mexican-American War that expanded U.S. territory to the Pacific. Cataloged by Cuds on Coins, DC-100c-2009P-01 documents a minor die failure on modern dollar coinage where the large die face and high striking pressure can produce chips at stress concentration points. The Position B designation is essential for attribution, as the same catalog number in Position A represents a different coin from a differently oriented die pair.
