# Coins and postage stamps of Sealand

The Principality of Sealand, a self-proclaimed micronation founded on a former World War II fort in the North Sea, has issued a number of coins and stamps for collectors. These coins and stamps are denominated in "Sealand dollars" (SX$). Sealand coins can be considered souvenirs only or "rounds" since they do not circulate anywhere and are not accepted as currency by any nation.

## History

Sealand began commissioning coins in 1972. The first to be minted was a SX$10 coin with a mintage of 2000. More coins were minted in 1975 and 1977, introducing the SX$20 and SX$100 coins. The SX$10 was minted in 925‰ fine silver, the SX$20 was minted in silver, and the SX$100 was minted in 900‰ fine gold.
In 1991 the "Sealand rebel government" (see Forcible takeover) minted antiqued silver SX$100 coins.
In 1994 the "Treasures of the Sea" Sealand dollars were minted, with an orca on the reverse. The SX$0.25, SX$0.5, SX$1, SX$2.5 and SX$5 were also introduced. The SX$0.25 was minted in bronze and 999‰ fine silver; the SX$0.5 was minted in cupronickel and silver; the SX$1 and SX$2.5 in bronze, silver and gold; and the SX$5 was minted in gold.
Sealand printed stamps in 1969 and 1970.
In 2020, a Sealand stamp was sent into space.

### Error coin

In 1994, fewer than 150 copies of the half dollar were accidentally cut with a scalloped edge instead of the normal reeded one. This is Sealand's only error coin to date. In addition, a mule of a Navy SEALs commemorative medallion was inadvertently struck, by the same private mint that produces Sealand's coins, using the reverse of a Sealandic half dollar. 75 of these were struck before the error was noticed.

### Rebel government coin

A rebel government, referring to itself as the "Sealand government in exile", seeking to occupy Sealand, issued a single commemorative coin in 1992.
