There is a new Android app for the collectors of Canadian coins. It has a catalog of about 700 coins with images, catalog prices, mintage, material, weight and so on. Also it helps you manage your coin collection (you can create lists like your wish list, trade list and own collection).
The app is on Amazon (http://goo.gl/4fLKm) and Google Play (http://goo.gl/2ymTP).
What do you think about it?
