As disclosed herein, a method for determining when a coin storage bin having a bottom and sides is filled to a predetermined percentage of the volume of the coin storage bin comprises: determining a coin volume for a coin entering the coin storage bin, adding the coin volumes for each coin entering the coin storage bin to provide a running total volume of all coins entering the coin storage bin, comparing the running total volume of all coins entering the coin storage bin with the volume of the coin storage bin, and determining when the running total volume of all coins entering the coin storage bin is greater than or equal to the predetermined percentage of the volume of the coin storage bin. The volume for a coin can be determined from information provided by a coin acceptor, where the information is thickness, diameter, weight, or a combination comprising at least one of these.
