Following the restoration of the monarchy in 1660, the coinage was reformed, with the ending of production of hammered coins in 1662. The "guinea" was introduced in 1663, soon followed by the , 2 and 5 guinea coins. The silver coinage consisted of denominations of 1d, 2d, 3d, 4d and 6d, 1/–, 2/6 and 5/–. Due to the widespread export of silver in the 18th century, the production of silver coins gradually came to a halt, with the half crown and crown not issued after the 1750s, the 6d and 1/– stopping production in the 1780s. In response, copper 1d and 2d coins and a gold guinea (7/–) were introduced in 1797. The copper penny was the only one of these coins to survive long.
