George III (1760-1820) halfpenny, 1806.
Found at Elcho Castle, this copper coin offers an example of the so called Soho Mint coinage, issued by Matthew Boulton's mint in Birmingham.
On the obverse is a robed laureate bust of King George III. From 1799 to 1807, the change in the reverse design transformed Britannia into a symbol of Britain's ever increasing maritime power, holding an olive branch and a trident, with a shield resting beside. A small ship lies in the left background.
On the obverse, the Latin inscription reads: GEORGIUS III DEI GRATIA REX. This translates as: 'George III by the grace of God King'. The reverse quotes 'BRITANNIA', that is 'Britain'.
The shortage of small change was giving the country big problems at the time. Allegedly by 1780, only 8% of copper coins in circulation were genuine regal coins. The Royal Mint contracted Matthew Boulton to produce copper coinage in 1797 and the minting of halfpennies was outsourced to Birmingham to combat counterfeiting. It is said the first halfpenny was produced during the reign of Edward I in the 1200's and was then abandoned in 1969 during the change to the decimal coinage.
