The Isle of Man has its own circulating coinage, which is used in parallel with the British Pound Sterling; it also issues an extensive range of commemorative coins for collectors, as well as bullion coins in a variety of formats and designs for investors in precious metals.
These coins are usually in internationally popular standard formats, but some (listed below) are in non-standard sizes. They are considered Non-Circulating Legal Tender (NCLT) because they are "premium" editions released at prices much higher than their bullion value. |
