Abstract: The invention relates to a method of cashing up and collecting money from coin-operated machines and an arrangement of coin-operated machines for carrying out the method. The coin-operated machines which are in association with a money changing machine to form a group. A counter is provided which registers the amounts of money arising, such as the value of coins inserted into gambling machines. Excess coins arising in the machines during play are first fed, unsorted, to the money changing machine, and when its set filling level is reached, are fed to a coin strongbox. It is possible to sort out and feed at least one preferred type of coin, such as a high value coin or a low value coin, to the money changing machine and to feed remaining excess coins unsorted to a coin strongbox. The value of coins being transferred by the coin sorting device is continuously added and stored separately from the coins to be paid out and to be fed into a coin strongbox of the change dispenser.
