Coin type: Half Guinea
Description

The half guinea gold coin of the Kingdom of England and later of Great Britain was first produced in 1669, some years after the Guinea entered circulation. It was officially eliminated in the Great Recoinage of 1816, although, like the guinea, it was used in quoting prices until decimalisation.

The value of the guinea had fluctuated over the years from twenty to thirty shillings, and back down to twenty one shillings and sixpence by the start of George's reign. A Royal Proclamation of December 1717 fixed the value of the guinea at twenty one shillings. The value of the half guinea was thus fixed at ten shillings and sixpence (10s6d).
