George III  1760 - 1820
This was the first copper penny to be minted in
Britain.  Introduced in1797 and only struck in
that year, it weighed one ounce, was known as
a cartwheel, and measured the equivalent of
36mm diameter by 3mm thick. A twopence
which weighed two ounces was also struck.
The price of copper was very high and, in big
demand due to the Napoleonic wars,
consequently no more copper pennies were
struck until 1806
