2025 World's Most Expensive Stamps - Benjamin Franklin Z-Grill Silver Proof Coin
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.
