The rarity of a 1971 Eisenhower dollar depends entirely on the specific version of the coin. The most common versions, intended for general circulation, were struck at the Philadelphia and Denver mints. These coins are made of a copper-nickel clad composition, contain no silver, and were produced in massive quantities, with over 116 million minted between them, making them not rare at all.
The versions that are considered scarcer are the collector coins struck at the San Francisco mint, which are identifiable by an "S" mint mark. These coins are composed of 40% silver and were sold directly to collectors in two finishes: an uncirculated version (often called a "Blue Ike") and a proof version ("Brown Ike"). These silver dollars had significantly lower mintages than their clad counterparts; approximately 6.9 million uncirculated and 4.2 million proof coins were struck. While more limited in number, their availability still makes them relatively accessible to collectors.
True rarity for a 1971 Eisenhower silver dollar is found in coins with exceptional condition or specific errors and varieties. A coin's grade is a primary factor; a 1971-S silver dollar in a very high state of preservation is much rarer than a typical example. The most significant rarity, however, lies with specific die varieties. Examples include the 1971-S Proof "Peg Leg," which features a missing serif on the "R" in LIBERTY, making it a sought-after variety. Even rarer is the 1971-S "No S" Proof, an extremely scarce error coin struck without the mint mark, believed to be a transitional error with only one known authenticated example. It is these specific varieties and high-grade conditions that elevate a 1971 Eisenhower dollar from a common collectible to a genuine rarity.
