1972-S Doubled Die Reverse WDDR-001
ErrorDescription
As the primary numbered variety in the Wexler sequence — WDDR-001 — this proof Kennedy Half Dollar from the 1972-S San Francisco Mint production holds the distinction of being the first-cataloged (and typically the strongest or most significant) doubled die reverse for the date. The WDDR-001 designation under cross-reference 1972-S 50-cent Proof WDDR-001 establishes this die as the anchor point for the 1972-S DDR census, which has grown to include at least six separate varieties (WDDR-001 through WDDR-006), making this date one of the most prolific sources of proof DDR varieties in the entire Kennedy Half Dollar series spanning from 1964 to the present. The 001 position in the sequence conventionally indicates either the first variety discovered or the variety displaying the most prominent doubling characteristics, giving it particular significance for collectors seeking the strongest representative example of the 1972-S DDR phenomenon. Proof production specifications for the 1972-S half dollar included 40% silver clad composition at 11.5 grams, with specially polished dies imparting mirror fields and the multiple-strike proof process ensuring deep, sharp impressions of every design element — including any secondary hub impressions present on the die. The Wexler Team attribution confirms independent expert verification of this variety's existence and distinctness from other 1972-S DDR dies. Frank Gasparro's reverse, adapted from the Presidential Seal of the United States, features a heraldic eagle clutching olive branch and arrows, surrounded by a ring of 50 stars and flanked by UNITED STATES OF AMERICA and HALF DOLLAR — a design with abundant fine detail where even subtle hub offset can produce visible doubling signatures. Collectors should examine the design elements under 5x to 10x magnification to locate the specific doubling zones.
