Valued at 5 cents each, 40 nickels combined are equal to the value of $2. Each dollar is worth the equivalent of 20 nickels. The nickel is one of five types of coins produced by law by the U.S. Mint.
In addition to the nickel, the U.S. Mint produces pennies, dimes, quarters, half dollars and $1 coins, any of which can be combined to reach a total value of $2. The U.S. Mint has produced nickels since its inception. Coin collectors appraise rare and old nickels at a greater amount than their 5-cent face value, with some nickels being worth far more than $2.
