The mass of a nickel, which is a five-cent coin in the United States, is 5.0 grams.
This mass has remained consistent since the coin was last revised in 1866. The nickel is composed of 75% copper and 25% nickel, which gives it both durability and a distinct appearance. When you look at a nickel, you can see the profile of Thomas Jefferson on one side and Monticello on the other. The weight of the nickel is important for both everyday transactions and for collectors, as it helps in determining the coin’s value and authenticity.
