Quarter coin collection allows you to manage your collection of US quarter dollar coins from the "50 states" and "America the Beautiful" series.

For each coin is available an image of its reverse, its date of issue, the mintage per mint, the state it represents as well as the flag of this state.

Coins can be sorted by states, date of issue, mintage and for the "America the Beautiful" series by name and type of site they represent.

It is possible to enter the number of coins or simply identify them as owned. It is also possible to differentiate between mints, in this case the coins are entered by mint.

4 filters are available:
- All: all coins are displayed.
- Got: owned coins are displayed. You only need to have one coin even if differentiation by mint is activated.
- Need: unowned coins are displayed. If the differentiation by mint is activated, you must have the coins for each mint so that they are not displayed.
- Swap: this filter is available if the number of coins is activated. Coins owned more than once are displayed.
