Keep track of all your rare and valuable coins and their value as well as the value of your whole collection.
Display your coins grouped by denomination, year or country. Research the value of each coin. The images you create of your coins are stored in CoreData so you don't need to worry about accidentally deleting the image you scan or photograph.
Added a new menu item "Import/Export" so you can create a backup file or use the file to put your coins on multiple iOS devices. If you have a large number of coins the text file will be larger than most email accounts allow, so you will have to use the Mail Drop option which uses iCloud. You can also use it to update other iOS devices when you change values on one device.
