The item in question is a United States dollar coin struck in 1973 at the San Francisco Mint. It features a portrait of President Dwight D. Eisenhower on the obverse and an image of an eagle landing on the moon on the reverse. These coins were intended to honor both Eisenhower and the Apollo 11 moon landing.
These particular coins hold significance due to their composition and mintage. While circulating Eisenhower dollars were made of copper-nickel clad, the “S” mint mark specimens were struck in 40% silver for collectors. This silver content, coupled with their status as a commemorative coin, makes them appealing to numismatists and those interested in American history. Their value exceeds face value depending on condition and demand.
