The U.S. Mint struck several different 1976-S Proof Eisenhower Dollars this year. it struck this Clad Type 1 which has thicker lettering and no serifs at the end of the lettering. The Type 2 Clad has thinner letters with serifs on most letters. Finally it also struck a 1976-S Proof Eisenhower Dollar but made out of Silver. All the three different types are very common up to PR67 or 68 Deep Cameo condition. In PR69 Deep Cameo they are a little more challenging to locate but still out there with proper searching. In PR70 condition all three different Types are really scarce and any example in perfect PCGS PR70 Deep Cameo condition usually commands thousands of dollars or more.
