Principality of Sealand

The Principality of Sealand is a micronation located on HM Fort Roughs, a former World War II Maunsell Sea Fort in the North Sea 10 km (six miles) off the coast of Suffolk, England.

Since 1967, the facility has been occupied by former radio broadcaster British Army Major Paddy Roy Bates; his associates and family claim that it is an independent sovereign state. External commentators generally classify Sealand as a micronation. It has been described as the world's smallest nation. Sealand is not currently officially recognized as a sovereign state by any United Nations member.

Several dozen different Sealand coins have been minted since 1972. In the early 1990s, Achenbach's German group also produced a coin, featuring a likeness of "Prime Minister Seiger". Sealand's coins and postage stamps are denominated in "Sealand dollars", which it deems to be at parity with the U.S. dollar. Sealand first issued postage stamps in 1969, yet no stamp issues have been made since the start of the 21st century, and Sealand is not a member of the Universal Postal Union, therefore its inward address is a PO Box in the United Kingdom.
