The 1957 Denver nickels are a type of five-cent coin minted by the United States Mint. These coins are part of the Jefferson Nickel series, which features a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The 1957-D variant, marked with a "D" mint mark, is notable among collectors for its relatively high minting numbers compared to other years, though well-preserved examples can still hold significant collectible value. Coins from this era are often sought after for their historical significance and as part of complete Jefferson Nickel sets.
