2010P-10DEO-002T Trail Die Obverse

Description

Documented by Trail Dies and discovered by Jean Lee, the 2010P-10DEO-002T is a trail die obverse variety found on the 2010-P Roosevelt Dime. Trail die varieties represent a specialized class of die anomaly where design impressions are faintly transferred between die components during the manufacturing process, leaving subtle raised trail marks on struck coins. Die markers place this in Stage B (mid-die state): the obverse shows no noted markers in MDS, while the reverse in MDS exhibits a die scratch running from the last U in PLURIBUS down to the M in DIME — a cross-inscription die scratch that traverses multiple design elements. The catalog designation 10DEO-002T follows the Trail Dies system where 10D indicates dime denomination, EO indicates obverse (error on obverse), 002 is the sequential catalog number, and T confirms the trail die classification. John R. Sinnock's Roosevelt Dime obverse portrait of Franklin D. Roosevelt has been in continuous use since 1946, with the current clad version produced since 1965 when silver composition was discontinued. The 2010-P was struck at the Philadelphia Mint in copper-nickel clad composition (outer layers of 75% copper and 25% nickel bonded to a pure copper core), weighing 2.27 grams at 17.9 mm diameter. The die scratch from U of PLURIBUS to M of DIME on the reverse provides a diagnostic marker independent of the trail die effect itself, confirming the specific working die and its mid-die state condition when the trail impressions were present.
