Coin Collection helps users interested in collecting a set of coins keep track of which coins they already have. This comes in handy if you are trying to collect the 50 U.S. State Quarters, for example, and want to check whether the quarter you just got back in change from the vending machine should be highly guarded until it can be placed in your collection.
The current version only supports U.S. currency, specifically:
Note: The DC and Territory coins are in the app – when you create a "State Quarters" collection, check the "Include the quarters for D.C. and the U.S. Territories" box. Unfortunately, though, if you created a collection without this box checked, there isn’t a way to add them in later. :( Sorry for the confusion.
