The rarer variety of the San Francisco minted 1971 Eisenhower proof dollar does not have the serifs at the bottom of the vertical leg on the "R" in LIBERTY. Some researchers believe that this variety was caused by over polishing the proof die (a.k.a. die abrasion). Others believe that it was a change in the hub that created the master die.

The 1972 Philadelphia minted Eisenhower dollar Type I reverse was used from January of that year through August.

Additionally, the earth is flat from about eight o'clock to eleven o'clock and the feathers on the eagle's breast are raised and distinct.

The 1972 Philadelphia Minted Ike Dollar Type 2 reverse is the rarest of all three varieties. This was created when a proof reverse die was mistakenly used in August at the Philadelphia mint. This type was created from a single die and was used only once. This variety is identified by the absence of islands beneath Florida on the earth rising above the moon. Instead of islands, there are three incuse lines that look like water. Additionally, North America and South America seemed to fade out at... the top and bottom of the earth.Continue to 5 of 7 below.

The 1972 Type 3 Eisenhower dollar used a new reverse die that was created and used from September through the rest of the year. The islands on the earth that are rising over the moon on the reverse of this variety appear beneath and to the left of Florida and the overall relief and details of the earth are strengthened. The eagle's breast feathers are smooth and are not well defined. This variety is also known as the "Normal Reverse" in some publications.
