On its website, the Gibraltar Philatelic Bureau also said that the new stamp “will be tied to the release of a blockchain based Digital Collectible, or non-fungible token (‘NFT’) counterpart, exclusively produced by Coinsilium in collaboration with Vietnam-based RedFOX Labs Joint Stock Company (RedFOX).”
This is Gibraltar’s second cryptocurrency stamp. The first was issued May 15, 2018, in what the bureau called a “personalized stamp sheet of four.” The four 50-penny stamps in that sheet share the same design showing the Rock of Gibraltar.
