How to Use the Coin Calculator

This tool is designed to help you quantify your physical currency without the need for manual tallying. Simply enter the number of coins you have for each denomination. The calculator automatically handles the math based on standard U.S. Mint specifications.

Understanding US Coin Denominations

  • Penny: The smallest unit of currency, valued at $0.01.
  • Nickel: Composed of copper and nickel, valued at $0.05.
  • Dime: The thinnest and smallest physical coin, valued at $0.10.
  • Quarter: The most commonly used coin for vending, valued at $0.25.
  • Half Dollar: Larger coins featuring JFK, valued at $0.50.
  • Dollar Coin: Including Sacagawea or Presidential series, valued at $1.00.

Example Calculation

If you have a jar containing 50 pennies, 10 nickels, and 4 quarters, the calculation works as follows:

  • (50 × 0.01) = $0.50
  • (10 × 0.05) = $0.50
  • (4 × 0.25) = $1.00
  • Grand Total: $2.00 (64 coins)
