A coin processing machine includes a first stationary finger and a second stationary finger spaced from the first stationary finger and defining a first opening between them to receive a stream of singulated coins. The first opening is larger than the largest diameter coin to be processed by the coin processing machine. A movable third finger is spaced from the first finger and defines a second opening downstream from the first opening. Larger-diameter coins move the third finger to permit the coins to move through the second opening and past the third finger. Smaller-diameter coins that pass through the first opening and engage the third finger are directed towards the first finger before reaching and passing through the second opening.
