The British "Cartwheel" Penny and Twopence was only ever minted in 1797.
Due to Britains ongoing expenses with various wars in the late 18th and early 19th centuries, there were very few silver or copper coins minted, subsequently there were a great many privately minted tokens and counterfeit coins produced.
To overcome the problem, undustrialist Matthew Boulton proposed that Pennies and Twopences should be made to contain their value in copper and that the coins would have thickened raised edges to prevent them from wearing easily.
The thickened raised edges gave the coins the appearance of a cartwheel, hence the name.
The British "Cartwheel Penny" and "Cartwheel TwoPence" were only issued in 1797. The Isle of Man "Cartwheel Penny" and "Cartwheel Halfpenny" were issued in 1798 and 1813. Any of these coins in excellent condition could be considered valuable.
If you refer to the GEORGE III 1797 "Cartwheel" Penny and Twopence, they are both made from copper and are of almost identical appearance, the Penny is a little over 30 mm in diameter and the Twopence is much larger at about 40 mm in diameter.
Isle of Man "Cartwheel" Pennies and Halfpennies were only issued in 1798 and 1813.
