The official coinage of the Isle of Man are denominated in Manx pounds. From 1971 to 2016, coins of the Isle of Man were minted by Pobjoy Mint Limited. Since 2017, coins of the Isle of Man have been minted by the Tower Mint.
Due to matching appearance and value of pound sterling coins, these coins often appear in circulation within the United Kingdom. However, they are not legal tender there. Conversely, the Isle of Man does recognise pound sterling coins.
As well as producing non-circulating commemorative designs, the Isle of Man regularly changes the designs on the circulating coins.
The Manx pound matches the pound sterling and went decimal in 1971, with the UK, however since this date the Isle of Man has been at the forefront of coin innovation: The £1 coin was introduced on the Isle of Man in 1978, 5 years before the United Kingdom's equivalent, and there is currently a circulating £5 coin.

|1978-1982: Triskelion on map
:Reverse design: the Triskelion set over a map of the island, with fleur-de-lis on either side and the legend “· ISLE OF MAN · ONE POUND” around the edge, along with small die letters (e.g. AA, AB) usually placed on the map near the “N” in ONE. While this core design remains unchanged, several special variations appear by year: the 1979 issue includes a small triskelion in a circle above the “O” in POUND to mark the millennium of Tynwald, with some versions instead showing crossed oars; 1980 coins may carry additional inscriptions commemorating events such as the Isle of Man TT and the Daily Mail Ideal Home Exhibition; and certain 1982 pieces replace die letters with a “baby cradle” privy mark celebrating the birth of Prince William.
