Abstract
Abstract A coin sorter (10) of the type wherein coins are sorted by the combination of a sorting head (22) and rotated resilient disc (12) in which the inner edge of the coins are radially referenced as they rotate, and coins of a discrete diameter of ejected at discrete circumferential points by a series of ramp-slot (S1-S6) combinations in which the radially positioned ramp depresses a discrete diameter of coin into a slot. The slots (S1-S6) are configured to direct coins caught in a slot outward.
