The images of this copper coin came in from a lady who wished to remain anonymous. It was found many years since by her nephew in a stream in the Derbyshire countryside and I was asked to provide a full ID.
I was told that the coin measures 1.1 inches in diameter. It is badly worn but on the obverse is a head and on the reverse the figure of Britannia. From its size and the remaining detail I can say that this is a halfpenny of George III and the date will be either 1806 or 1807.
This is one of the early 19th century copper coins most frequently found by detectorists. The second date turns up less frequently but both were struck in very large numbers
