1972 Type 1

The 1972 Type 1 is the most common of the three Philadelphia reverse varieties for the year, struck from the original low-relief reverse hub the Mint had carried over from the 1971 production. Philadelphia's combined 1972 output across all three types was 75,890,000 pieces; the Type 1 share is the bulk of the run, since the mid-year shift to the Type 2 and then Type 3 reverses came only after the Type 1 had already filled most of the year's production order. The reverse Earth on the Type 1 sits in low relief with indistinct continental outlines and Florida barely visible against the surrounding ocean.

Strike quality on the 1972 Type 1 is typical of early Philadelphia work for the series, with the moon surface and eagle coming up cleanly on coins from early die states and the Earth detail soft by design rather than by die wear. Diagnosing a Type 1 from a Type 2 or Type 3 turns on the Earth itself: hold the coin under raking light at five to ten power magnification and compare the continental relief to PCGS, the Professional Coin Grading Service, and NGC reference photos. The Type 1 reads as a featureless globe in profile; the Type 3 shows a clearly three-dimensional Earth with sharp Caribbean detail. Most surviving examples grade MS63 to MS65 from broken bags, with MS67 examples genuinely scarce.

This is a regular common date by mintage and the easiest of the three 1972 Philadelphia varieties to acquire. Collecting interest sits primarily in the contrast with the scarce Type 2, which trades at a strong multiple, and in completing the trio of reverse varieties for a 1972 type-set within the series.
