2012P(SAC)-100DER-001T Trail Die Reverse

Description

The first documented trail die reverse for the 2012 Philadelphia Native American Dollar, this Position A variety was discovered by Jean Lee and records ghost impressions on the reverse die face rather than the obverse. While trail die obverses show faint traces on the Sacagawea portrait side, a trail die reverse carries phantom design elements on Thomas Cleveland's trade routes reverse featuring the horse and rider motif. Reverse trail dies can originate when a working die previously used for a different series retains microscopic impressions, or when adjacent coins in the feeding mechanism transfer faint images through the striking process. The Position A orientation — with the obverse die on the anvil — defines the edge lettering relationship on this manganese-brass clad dollar. As the first cataloged trail die reverse for the 2012 Sacagawea-type issue, DER-001T establishes the baseline entry in the census. Jean Lee's systematic documentation across both obverse and reverse faces, and across both die positions, provides a comprehensive record of trail die production anomalies at Philadelphia during 2012 Native American Dollar coinage.
