Z Grill
The Benjamin Franklin Z-Grill is a postage stamp issued by the United States Postal Service in 1868 depicting Benjamin Franklin and is considered the rarest US stamp due to the embossed "Z-Grill" on the back. A "Z-Grill" is a specific pattern of tiny squares embossed into the paper and visible on the back of the stamps.
