Coin sorters rely on the fact that coins are all different sizes. The machines work by passing batches of mixed coins over holes of varying sizes so that the coins drop through in a specific order. The coins drop into separate containers according to their denominations, and this makes it easier for users to bag them in readiness for banking. Most coin sorters are currency specific because different currencies often have similarly sized coins of different values. Some machines are, however, able to sort foreign coins as long as the coins are within specified diameter and thickness ranges.

Many coin sorters are also coin counters. Such machines use a number of sensors to count the coins as they are sorted and can be set to stop once the number of coins reaches a set limit. Some advanced coin sorters can also identify and remove foreign or damaged coins. They do this by analyzing the coins’ metallic makeup using a complex sensor and comparing the results against a database of known and accepted coins. This function is especially useful for charities and other organizations that receive significant numbers of foreign coins.
