Excellent

Best coin app. Does everything I need for my State Quarter collection.

Perfect, easy to use, but can you please.....

I love this app. It’s easy to use easy to navigate but would love to have the proof cloud and silver coins added to the list. And it would be even better if you can add the “S” BU quarters the mint has made from 2012 to now. If you would add these coins to the list, this app would be a five star perfect record keeper for all coin collectors. Thank you!!!!

Perfect

So nice to find an app that does exactly what it says it will do, attractively and easily. I’m not a coin collector, but I do collect the state, territory, and state park quarters. I’ve been collecting them as I find them, so none of them are “mint” but they are still worth 25 cents a piece so it’s been a fun excuse to save up pocket change. I keep them in a set of Whitman folios, which gives you space for the P and D mints, and so I love that this app lets you check off one from each mint. I also like the photos and accompanying paragraph about the image on each coin. Very nice job creating a simple, useful app. I’m very happy with my purchase.
