The world's smallest coin is a 1 millimeter coin from the Principality of Sealand, a micronation located on an offshore platform in the North Sea. This coin was issued to commemorate the 40th anniversary of Sealand's independence in 2007. It is considered a novelty item rather than a practical form of currency.
