The coin in question is a United States dollar coin minted in 1972 at the Denver Mint. It belongs to the Eisenhower dollar series, which was introduced to honor President Dwight D. Eisenhower and commemorate the Apollo 11 moon landing. The “D” mint mark signifies its production at the Denver Mint, distinguishing it from those minted in Philadelphia (no mint mark) or San Francisco (S mint mark). Its composition is primarily copper and nickel, clad around a core of pure copper.
This particular coin holds a degree of collectibility depending on its condition and any existing errors. While millions were produced, uncirculated examples and those with specific minting errors can fetch prices exceeding their face value. The series as a whole represents a significant period in American numismatic history, marking the transition away from silver coinage and reflecting national pride in space exploration.
