The Benjamin Franklin Z Grill or Z Grill stamp from 1868 is one of the rarest and most valuable US postage stamps of which only two exist. It has a face value of one cent and is one of the most expensive postage stamps in the world.
With this and other American postage stamps a waffle indentation ( English grill ) was stamped as a security measure in order to make it difficult to use it again. This postage stamp has a Z grill based on the William L. Stevenson classification of postage stamps grills.
