In 1816, a new silver coinage was introduced in denominations of 6d, 1/–, 2/6 (half-crown) and 5/– (crown). The crown was only issued intermittently until 1900. It was followed by a new gold coinage in 1817 consisting of 10/– and £1 coins, known as the half sovereign and sovereign. The silver 4d coin was reintroduced in 1836, followed by the 3d in 1838, with the 4d coin issued only for colonial use after 1855. In 1848, the 2/– "florin" was introduced, followed by the short-lived double florin in 1887. In 1860, copper was replaced by bronze in the farthing (quarter penny, d), halfpenny and penny.
