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.
One of the formats used is the large two ounces of silver, abbreviated as 2oz Ag, where Ag comes from the Latin word for silver, Argentum. The coins are considered Non-Circulating Legal Tender (NCLT) because they are "premium" editions released at prices much higher than their bullion value.
The Mint says about this coin:
The modern Noble coins have been issued by Isle of Man since the early 1980’s. Despite their world-wide popularity, they were not minted every year. This had added to the coins allure as previous issues can be difficult to find. With the 2022 edition, CIT is extremely proud to bring an emended design to the Noble. It is the first enhancement to the actual design since it was introduced back in 1983! Thanks to the smartminting technology the famous Viking long ship on the reverse shows more details as certain elements have been modernised. You can almost feel the wind when you look at this coin!
Interestingly, Nobles are legal tender but they do not have a fixed face value; instead, like the Krugerrand or Mexico’s Libertad, they are legal tender to the value of their precious metal content.
