1974-S Variety WMHR-001

Description

Sharing the same master hub origin as the 1974-D WMHR-001, the 1974-S Eisenhower dollar proof WMHR-001 carries identical doubling characteristics — a spread towards the center on ONE DOLLAR, the designer's initials (FG for Frank Gasparro), and the lunar craters — because both descend from the same doubled master hub that propagated this variety across multiple years of production. Cross-referenced as CONECA: SD-2-R-II-C+VI, this proof issue demonstrates how master hub doubling transcends individual mint facilities and striking formats: the same fundamental doubling appears on both Denver business strikes and San Francisco proofs because both production lines drew their working dies from the same master hub inventory. The Wexler Team's documentation notes that working dies with this exact doubling exist for 1974, 1977, and 1978, with differences in appearance resulting from progressive wear through the die manufacturing hierarchy — master hub to master die to working hub to working die — and finally from individual coin wear. San Francisco proof Eisenhower dollars were struck on specially prepared planchets using polished dies, creating mirror-finish surfaces that may render the centripetal spread more visible than on Denver business strikes, where the standard satin finish provides less contrast for detecting subtle hub doubling. Frank Gasparro designed both the obverse (Eisenhower portrait) and the reverse (Apollo 11 eagle landing on the Moon), and the lunar craters provide particularly useful diagnostic surfaces for master hub doubling because their irregular topographic detail amplifies even slight displacement between hub impressions. Cross-referenced as Wexler Variety ID: 1974-S $1 Pr WMHR-001, this proof counterpart to the Denver business strike provides collectors with the opportunity to examine the same master hub doubling under the enhanced surface conditions of proof production, potentially revealing nuances that are less visible on the business-strike version.

Attribution History

• Discovered by Various Cross References: CONECA: SD-2-R-II-C+VI Comments: Because this was a master hub it was intended to be used over a period of several years. Working dies with the exact same doubling are known to exist for the years 1974, 1977, and 1978. Differences in the appearance of the doubling will result from master hub wear, master die wear, working hub wear, working die wear, as well as coin wear.
