The U.S. did not mint nickels until 1866. Please check your coin again and post a new question with more details that help to ID it. If the coin says "half dime" on the back it's not a nickel even though it's worth five cents. The half dime was a different series. If it's the size of a modern nickel you may be reading the date incorrectly.
50 Pence is half of a british pound. As for the coin, it was first the 10 shilling gold coins such as the half-sovereign after the first world war, the half-sovereign stopped circulating widely and was mostly replaced by the 10 shilling note by then. In preparation for the decimalization of the pound in 1971, the 50p coin was made from 1969 to replace the 10 shilling note, the idea was the coin would last much longer in circulation than the 10 shilling note would. The 50p is 75% copper, 25% nickel and is a heptagonal shape. From 1969-1994 it was the original, large size when it was replaced by the current size in 1997. The large-sized 50p coins are no longer legal tender in the UK .
