Here is the Numista listing: https://en.numista.com/12119 Could you post a better picture of the obverse, as that seems to be where the issue is found?

Sap Moderator Australia 16808 Posts	Posted Today 6H 21M ago The coin is made of debased-silver (.550 fine), which can turn odd colours naturally. I would assume it's "just toning", rather than some kind of mint error. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

I would assume it's "just toning", rather than some kind of mint error. The Royal Mint had just switched production of British coins from .925 to .500 silver in 1920, and I think they had problems with the alloy: many British coins of 1920-27 show this effect. Here's a rather extreme example on a 1923 halfcrown: My Trade List: https://goccf.com/t/194596 My Wants List: https://goccf.com/t/191710 Report this Post to the Staff

Thanks for that information, NumisRob! I have several British coins from that time period that I haven't photographed because I thought that they were "stained".

ken key New Member United Kingdom 8 Posts	Posted Today 1H 19M ago Thanks every one..as it's a low value coin I did clean it witch I know is a cardinal sin but my intrest in the copper streak kinda out weighd the value of the coin,so I can say 100% it's not natrual toneing...so ime thinking just a badley mixed alloy due to low silver content alloy mix.ille keep digging to see if theres any more of tge same coin...seems genuine though,hopefully & Report this Post to the Staff
