We only list UK decimal coins on the site, if your coin isn’t listed it is likely that it is a coin from another British Isle like Isle of Man or Jersey, or from an Overseas Territory like Gibraltar. Due to the lower populations of places like these, the coinage generally has significantly lower mintages, making the coins more sought after. Coinage like this is not actually legal tender in the rest of the UK, but they can easily slip into UK circulation. There is limited information for these coins on the web, but please get in touch and we will be able to assist with gathering further information for you.
