Finally the spare change jar has been upgraded! This digital bank sorts pennies, nickels, dimes and quarters into their own coin tubes inside the jar. When a coin tube becomes full, coins will slide over a patent pending AccuWedge which allows excess coins over the amount of a full roll to fall into the Coin Chamber. Plus, it keeps track of your change. Now you'll know how much you've saved after emptying your pockets from the morning coffee change each day. Bank can store hundreds of coins and save until you're ready to spend. Requires one AAA battery, not included.
