1973-D

The 1973-D matches the 1973 Philadelphia at 2,000,000 pieces, also released only through the Uncirculated Mint Set program. The two issues are the matched pair that defines the 1973 collecting profile: paired low mintages, paired Mint-Set-only distribution, paired Semi-Key designations, and no commercial release at either facility. The Treasury cut Denver production in lockstep with Philadelphia after two years of inventory build-up had demonstrated that the dollar was not going to circulate at the volumes the initial production plans assumed. Frank Gasparro's design remained unchanged, and Denver's dies carried the standard high-relief reverse hub already in service since 1971.

Mint Set distribution means the 1973-D survives almost exclusively in collector-grade examples from sealed sets, with PCGS, the Professional Coin Grading Service, and NGC populations clustering at MS65 and MS66. Strike quality is consistently sharp; Denver Mint Set planchets received careful die-pair attention, and the eagle, lunar surface, and Eisenhower portrait all come up cleanly. MS67 examples are scarce enough to anchor real premium pricing because the entire 2-million-piece mintage was preserved in collector packaging, leaving very little room for the upgrade pool that normally develops from broken Treasury bag releases. No major varieties are catalogued for the 1973-D.

The 1973-D is a Semi-Key issue and pairs naturally with the 1973 Philadelphia in date sets. Pricing trails the 1973 Philadelphia slightly because collectors typically reach for the no-mintmark date first, but the differential is narrow and tracks Mint Set break-out supply rather than any meaningful difference in absolute scarcity. Original 1973 Mint Sets that include both the 1973 and 1973-D remain the most efficient route to high-grade examples of both Semi-Keys, and certified MS66 examples are inexpensive enough that the date does not require budgeting decisions even in a registry-set build.
