Abstract: A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device includes an input receptacle for receiving a stack of bills to be evaluated and a single output receptacle for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to the output receptacle along a transport path. The device further includes a discriminating unit that evaluates the bills. The discriminating unit comprises two detectors positioned along the transport path between the input receptacle and the output receptacle. The detectors are disposed on opposite sides of the transport path so that they are disposed adjacent to opposite sides of the bills. The discriminating unit counts and determines the denomination of the bills. The evaluation device also includes means for flagging a bill when the denomination of the bill is not determined by the discriminating unit.
