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

by Wi*****, 2025-07-05

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!!!!
