Abstract: A plate is provided with a horizontal coin slot. The slot has a lower wall at an angle of about 45.degree. and a upper wall parallel to the lower wall. Two rails having facing coin-retaining grooves running end-to-end are attached to the rear of the plate at opposite ends of the slot. The grooves slope downwardly from the slot at the same angle as the lower wall of the slot. Desired coins follow the chute formed by the slot and grooves, while undersized coins and foreign objects fall between the rails. A coin-orienting member may be added above the rails to help orient the coin in the chute.
