My kids lost half my CoinAge coins so I decided to make something to keep them in. And what would be more appropriate than a treasure chest? (See the reference link for the coins.) Print the appropriate number of coin age coins, then print this chest to keep them in. Snap the lid on the body. Put the coins in and close the lid with the latch. When you want it to open simply insert a finger to move the latch a little and the lid will open.
