I know that pre-1920 silver coins were sterling silver 92.5% silver 7.5% copper, post 1946 they're cupro-nickel 75% copper 25% nickel and inbetween they were only 50% silver but they went through a couple of compostion changes.. I would like the know what other metals in what percentage were used during this time pleeeease
Also .. had no idea which topic to put this under

Full details of the composition and much more of British coins (as at 2000, I don't think they've changed since) here:
