1973

The 1973 was struck only for the U.S. Mint's annual Uncirculated Mint Set program, with 2,000,056 pieces released exclusively through that collector channel. By 1973 the Treasury had read the demand signal: two years of inaugural-period production had left Federal Reserve vaults full of unwanted dollar coins, and the public was not absorbing the new large-format dollar at retail. The 1973 mintage is roughly 38 times smaller than the 1972-D and roughly 24 times smaller than the 1972 Philadelphia output, the steepest year-over-year drop of any modern U.S. dollar series before the 1981 Susan B. Anthony halt.

Mint Set distribution means the 1973 survives in concentration at MS63 to MS65 grades from sealed sets rather than from broken bags. Strike quality benefits from the careful planchet selection that Mint Set production typically received: the eagle, the moon surface, and Eisenhower's portrait all come up cleanly on most examples. PCGS, the Professional Coin Grading Service, and NGC populations cluster at MS65 and MS66, with MS67 examples scarce enough to command material premiums because the entire mintage was confined to a single distribution channel. Authentication on the 1973 is straightforward: every legitimate example carries the standard Philadelphia obverse with no mintmark, and the Type 1, Type 2, and Type 3 reverse variation that complicates 1972 does not apply, since Denver-style high-relief reverse hubs were standard by 1973.

The 1973 is a Semi-Key issue and the standard collector entry point for the series after the 1976 Bicentennial Type 1 pair. Mint Set break-outs remain the dominant source, and pricing has held steady across the past two decades at a level well above the 1971 and 1972 dates. The matched 1973 P/D pairing is the most efficient way to acquire both Semi-Key Eisenhowers, and original 1973 Mint Sets that include both coins still appear at coin shows at small premiums above the sum of the individual coins.
