What is a ha-penny?

Answer 1

A colloquial term for a British half-penny, a ha-penny (pronounced "HAY-penny") is an obsolete coin worth 1/480th of a pound.

Originally there were two farthings to a half penny, two half pennies to a penny, 12 pennies to a shilling and 20 shillings to the pound. In 1968, however, this system (called the LSD system, after the abbreviations for pound ("£"), shilling ("s") and penny ("d")) was replaced by the decimal system (100 pence to the pound), although a final LSD set of coins was made for collectors in 1970.

A decimal half-penny worth 1/200th of a pound was produced for a few years, but is no longer in circulation.

The values of half-penny coins vary considerably. For information on a specific coin, please post a new question with its date.
