These New York Highway Patrol Police plates are made of aluminum and they have an applied sticker on each. The Police stickers had been applied over other state license plates when these were made. They have a hole to hang them as a charm or as a fob on a key chain or key ring. The backs are stamped ''Hong Kong''. The miniature license plates each measure 1-13/16'' x 15/16''. They are unused and appear to be in near mint to mint condition as pictured.
