Description

Description

In 1868, the United States issued an experimental series of postage stamps
featuring the grill pattern — a grid of embossed cuts designed to prevent reuse.
The variant with horizontal impressions, known as the Z-Grill, has survived in only
two copies. One is held in the collections of the New York Public Library, while
the other sold at auction in 2024 for a record $4.3 million. This coin faithfully recreates
the appearance of the stamp, highlighting its distinctive pattern and exceptional place
in philatelic history.
