1070 Penny – William I (William the Conqueror) - Silver penny of William the Conqueror, struck about 1070-1072 at the London Mint of moneyer Ealdgar. The Obverse shows a crowned King William facing, with a canopy of two columns. This is known as the 'Canopy Type'.
1189 Penny – Richard I - If you're looking for Richard's name in the legend then you may be disappointed as it says HENRICVS, as the coins were struck in the name and design of Henry II (and continued to be so in the next reign too).
1806 Halfpenny – George III - There had been a need for a circulation halfpenny since the reign of Charles II but due to the (relatively) high production costs mintage was sporadic. In 1797 the Royal Mint asked Matthew Boulton to produce copper coins at his Soho Mint in Birmingham and the Fourth Issue coinage included the halfpenny (and also twopence, penny and farthing).
975 Penny – Edward the Martyr - Silver Penny of Edward the Martyr, minted some time between 975-978. at the Lincoln Mint of Moneyer Rodbert. Edward became King in 975 when he was only about 13 years old and reigned until he was murdered in 978.
The 1797 Cartwheel Penny - The 1797 Penny is one of the most remarkable coins in British history. Its size earned the coin its nickname of the 'Cartwheel' penny. It has a diameter of 36mm, it is 3mm thick and weighs 28.35g. Compared to a modern penny it is almost twice the size, twice the thickness and a staggering eight times heavier!
