Detailed information about coin type: Halfpenny (Pre-decimal) from United Kingdom:
The British pre-decimal halfpenny (½d) coin, usually simply known as a halfpenny, was a unit of currency that equaled half of a penny or one four-hundred-and-eightieth of a pound sterling. Originally the halfpenny was minted in copper, but after 1860 it was minted in bronze. It ceased to be legal tender in 1969. The halfpenny featured two different designs on its obverse during its years in circulation. From 1672 until 1936 the image of Britannia appeared on the reverse, and from 1937 onwards the image of the Golden Hind appeared. Like all British coinage, it bore the portrait of the monarch on the obverse.
Before Decimal Day in 1971 there were two hundred and forty pence in one pound sterling. Twelve pence made a shilling, and twenty shillings made a pound. Values less than a pound were usually written in terms of shillings and pence, e.g. forty-two pence would be three shillings and six pence (3/6), pronounced "three and six". Values of less than a shilling were simply written in terms of pence, e.g. eight pence would be 8d.
