|---|---|---|---|
| Penny | 1.52 mm (0.06 in) | 15.2 mm | 5.98 in |
| Nickel | 1.95 mm (0.077 in) | 19.5 mm | 7.68 in |
| Dime | 1.35 mm (0.053 in) | 13.5 mm | 5.31 in |

| Dollar Coin | 2 mm (0.079 in) | 20 mm | 7.87 in |
Pick a coin and enter how many you have to get the height of the stack, its face value and its weight. Switch to the second mode to ask the other way round: how many coins fit in a height, such as a coin tube or a shelf.
Thickness is the U.S. Mint specification for each circulating coin. The stack height is the thickness times the number of coins; it assumes the coins lie flat on one another.
