Ah, the great Eisenhower dollar silver hunt! A noble quest that has confused many a treasure hunter. The answer to whether your 1971 Ike has silver is a classic "it depends on which one you have." It’s a tale of two very different coins.
The vast majority of 1971 Eisenhower dollars that were actually meant for circulation are, sadly, silver-free. These are the coins with a "D" mint mark for the Denver Mint or no mint mark at all for the Philadelphia Mint. They're made of a copper-nickel clad composition, which is basically a metallic sandwich with no precious filling. If you see a reddish-copper edge on your coin, you're holding one of these common varieties.
However, don't give up hope just yet! The U.S. Mint did create special collector's editions in 1971 that do contain silver. To find one of these, you need to look for a little "S" on the coin, indicating it was struck at the San Francisco Mint. These special "S" mint Ikes were never intended for circulation and were sold directly to collectors.
These silver versions, often called "Blue Ikes" and "Brown Ikes" after their original government packaging, contain 40% silver. The uncirculated silver dollars came in a blue envelope, while the proof versions with a mirror-like finish came in a hard plastic case inside a brown box. So, the simple rule is: if there's no "S," there's no silver. It's the key that unlocks the precious metal mystery of the 1971 Eisenhower dollar.
