A 10-pence coin is a coin issued by the British government. It is worth one-tenth of a pound, so it is analogous to a U.S. dime.
The 10-pence coin entered into circulation in 1971 as a replacement for the shilling in the old system of coins. In the old system, a shilling represented 12 pence, and a pound was 20 shillings. Prior to 2012, the coin contained 75 percent copper and 25 percent nickel. Since 2012, the coin has been made of steel plated with nickel. The version in circulation as of 2014 is smaller than the version introduced in 1971; the current coin was introduced in 1992.
