An improved bill stacker is described that effectively rolls incoming bills onto the stack. In one aspect of the invention, the bill stacker includes a housing that encloses a stacking plate that is arranged to support a stack of bills. A gripper is typically provided to grab the leading edge of an incoming bill and a stack roller is arranged to travel longitudinally relative the stacking plate to "roll" a newly received bill onto a top end of the bill stack (if present) o r the stacking plate when the first bill is being received. A variety of methods of stacking bills in a cash box using the concept of rolling an incoming bill onto the top of a stack are also described.
