A method and device for identifying small stacks of currency bills within a large stack of currency bills using a currency evaluation device. A stack of currency bills to be processed is received in an input receptacle and the bills are transported from the input receptacle, one at a time, past an evaluating unit to at least one output receptacle. The evaluating unit determines the face orientation of each of the bills. Next it is determined whether the face orientation of each of the bills matches a target orientation. If the face orientation of a bill matches the target orientation, the face orientation of that bill is maintained. If the face orientation of a bill fails to match the target orientation, the face orientation of that bills is reversed with a bill facing mechanism. Each of the bills are then stacked in the output receptacle. After a predetermined number of bills having a common face orientation are stacked in the output receptacle, the target face orientation is redefined. The bills continue to be processed in this manner until each of the bills are transported from the input receptacle.
