British coinage bronze is mostly-pure copper. The formula varied slightly over the years:
1860-1922: 95% copper, 4% tin, 1% zinc
1925-1954 (except 1943): 95.5% copper, 3% tin, 1.5% zinc
1943, 1961-1970: 97% copper, 0.5% tin, 2.5% zinc
"Melting" bronze personally isn't usually worth it, unless you're doing it on an industrial scale and/or have a specific need for the bronze alloy being melted.
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
