1977 Variety WMHR-001
ErrorDescription
Continuing the multi-year propagation of the same doubled master hub, the 1977 Eisenhower dollar WMHR-001 carries the identical centripetal spread on ONE DOLLAR, the designer's initials, and the lunar craters that originated on the master hub used across the 1974, 1977, and 1978 production years. Cross-referenced as CONECA: SD-2-R-II-C+VI and Wexler Variety ID: 1977 $1 WMHR-001, this entry demonstrates the remarkable longevity of master hub doubling — the same fundamental doubling event established during the master hub's creation continued to propagate through the die manufacturing hierarchy three years after its first documented appearance on 1974-dated Eisenhower dollars. Frank Gasparro's Apollo 11 reverse design features the Bicentennial reverse interruption in 1975-1976, after which the eagle-on-the-Moon design returned for 1977-1978, and the reappearance of the master hub doubling on 1977 coins confirms that the Mint returned to the same master hub inventory (or its descendants) after the Bicentennial interlude. Philadelphia struck approximately 12.60 million Eisenhower dollars in 1977, a reduced mintage compared to earlier years as the large dollar denomination's practical utility waned. The CONECA classification SD-2-R-II-C+VI designates this as a secondary die variety on the reverse combining Class II and Class VI doubling characteristics, confirming the complex multi-class nature of the original master hub misalignment event. By 1977, cumulative wear through the die manufacturing chain — master hub to master die to working hub to working die — would have progressively diminished the clarity of the doubling compared to 1974 specimens, making later-year manifestations generally subtler and requiring more careful examination to confirm. Collectors should compare 1977 specimens against confirmed 1974 examples to understand the wear-progression effect on doubling visibility.
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.
