1969-S Variety WMDO-001

Description

Classified as a Master Die Doubling Obverse variety, WMDO-001 of the 1969-S Proof Kennedy Half Dollar documents hub-level doubling that originated not on an individual working die but on the master die or hub from which all working dies for this issue were produced. This distinction is fundamental: because the doubling was imparted at the master die stage, every working die derived from that master carries the identical doubled image, and consequently every coin struck from those working dies exhibits the variety. This propagation mechanism makes master die doubling varieties inherently more available than conventional doubled dies, where only a single working die is affected. Cross-referenced as Wexler 1969-S 50-cent Proof WMDO-001, the variety appears on San Francisco Proof strikings of the silver-clad Kennedy Half Dollar — the 1965-1970 composition that combined a silver-clad outer layer with a copper core, replacing the 90% silver of the 1964 issue. Collectors should note that while WMDO varieties are legitimate catalog entries, their relative abundance compared to single-die doubled dies means they typically command more modest premiums in the variety marketplace.
