ABSTRACT:
A coin sorting apparatus counts and sorts coins by denomination in an efficient manner. The steps involve receiving the coins on a disc having a resilient surface and imparting rotational movement to the coins by rotating the disc with a stationary guide plate having a contoured surface spaced slightly over the resilient surface of the disc. The guide plate includes a recess for guiding the coins on the disc into a single file of coins. A referencing portion of the contoured surface is used to guide one edge of the coins in the single file along a prescribed path. The coins of a selected denomination are then counted as they are moved along the prescribed path. Coins of different denominations are discharged at different locations around the periphery of the stationary guide plate, and, in response to the counting, the discharge of the coins is interrupted.
