An improved feed arrangement is provided for use with currency handling apparatus in which cooperating action of an actively-driven drum roller is used for feeding bills stacked in an input bin along the bill transport path. The picker roller is rotationally driven, not by direct contact with the drum roller, but by contact with a pressure roller which is driven by the drum roll. In effect, the picker roller is rotated in a direction counter to the direction of the bill flow so that bills other than the bottom bill in a given stack are effectively pushed away from the direction of bill flow. The picker roller is, consequently, activated to function as a retard roller, as opposed to the conventional feeding action provided by picker rollers which are in counter-rotating contact with the drum roller about the direction of bill flow.
