1964 Doubled Die Reverse WDDR-016

Description

Cataloged by the Wexler Team as 1964 10-cent Proof WDDR-016, this Roosevelt Dime variety from the final year of 90% silver proof dimes displays two distinct forms of doubling on John R. Sinnock's reverse. Notching — shelf-like stepped edges on letter serifs — shows on UNITED, while extra thickness appears on the E PLU portion of E PLURIBUS UNUM. The combination of notching and extra thickness on different elements suggests the hub displacement produced varied manifestations depending on letter geometry and position on the die surface. A useful obverse die marker accompanies this variety: the 9 in the date carries a blunt, truncated tail rather than the standard tapering finish, providing an independent confirmation checkpoint visible without magnification. The 1964 proof Roosevelt Dime was struck at the Philadelphia Mint on polished planchets in 90% silver at 2.5 grams — the last year this composition appeared in proof dimes before the 1965 transition to clad coinage. Examine the serifs of UNITED under 10x magnification for shelf-like notching, then check E PLU for extra thickness. Verify the blunt tail on the 9 in the date as an obverse die marker.
