The Z Grill Myth: Why Your Stamp is Likely Not a Z Grill
The legendary Z Grill was a short-lived experiment. Postal workers pressed a special metal grid into the paper to absorb ink.
This prevented criminals from washing and reusing the stamp. The government applied this Z Grill to the 1-cent Franklin and the 2-cent Washington stamps.
Benjamin Franklin appeared on the lowest denomination at the time. A half-cent version simply never entered production during that specific era.
