Hopefully you've heard of the "cartwheel" before
Yes, in those time, british citizens (hope they forgive me in advance for being naughty) used to have a big penny
Yes , in 1797 CE, under the rule of George III a one once of copper penny has been minted. So big (with it's 2 pence brother) that it's been nicknamed cartwheel but just lasted for one year. It's a 36 mm and 28,6 grams chunk of copper, with a lovely draped and laureate bust of the king looking right. The reverse features Britannia seated left. Looks very much like a roman empire sestertius, reason why I wanted one, being mainly focused on roman coins
Thanks to Numista member and friend Kenobi, I could acquire the following one for a whim !
