Jefferson Nickels are a five-cent coin produced by the United States Mint, first issued in 1938. The 1966 Jefferson Nickel was minted in Philadelphia, Denver, and San Francisco, the latter being a key date for collectors due to its lower mintage. High-grade examples of the 1966 San Francisco mint-marked coins often attract collector interest, particularly in uncirculated condition. The coin features a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. Collectors often seek out specific varieties and grades to enhance their collections.
