I need some history and facts about a coin I found in my change its a 1980 us 25 cent on the reverse is a 1967 Great Brittan
Half Cent. Is it possible for the
Half Cent to have found its way in to the press. I believe that the us did make coins for other countries so the us would of had to made the half penny in 1967 then in 1980 struck it with the 25 cent. so is it possible for this to happen and is their any reference I could search for this coin error.
