Abstract: A coin sorting device for processing coins comprises an insertion device into which coins for sorting are insertable, a sorting device for sorting coins inserted via the insertion device, a plurality of receiving containers for storing sorted coins, an overflow collecting device for receiving coins after at least one receiving container has overflowed, wherein coins for reinserting into the insertion device are removable from the overflow collecting device and are reinsertable into the insertion device in a reinserting operation, and a counting device for counting coins inserted into the insertion device and coins passing into the overflow collecting device. A checking device is provided which is designed to check whether, in the event of a reinserting operation, the number of coins reinserted into the insertion device corresponds to the number of coins removed from the overflow collecting device.
