Cartwheel penny found with a metal detector
Thought this coin would make for an interesting comparison with the Cartwheel two pence coins I posted a few days ago. Above and below: A cartwheel one penny coin found with a metal detector. The pitting and corrosion on this coin is a testament to the hostile soil conditions found in many places in the UK, and the high quality copper used by the Soho Mint in its manufacture. On a long enough time line, copper coins and artefacts exposed to hostile soils conditions, not to mention the chemicals used in modern intensive farming, dissolve away to nothing.

They were created by Matthew Boulton at the Soho Mint in Handsworth, Birmingham in 1797. Eight of these cartwheel twopence coins, laid side by side, measure exactly one foot, an unusual sort of anti-counterfeiting measure. They weighed exactly 2oz a piece, the one penny weighing¬† exactly 1oz. At the time they were produced it is believed that as much as two thirds of the copper coinage in circulation in the UK was fake. They were also the first official British coins struck using steam power.
Cartwheel two penny coins produced by the Soho MintA quick and easy way of telling a cartwheel twopence from the one pence, without a side by side comparison, is to measure the thickness of the coin. A cartwheel twopence is 5mm or 1 fifth of an inch thick and the cartwheel one pence is 3mm thick.

Matthew Boulton and his Soho Mint also produced tokens for the East India Company. The millions of copper tokens salvaged from the wreck of the Admiral Gardner, wrecked on the Goodwin Sands on January 24/25, 1809, were produced at the Soho Mint on Matthew Boulton’s steam powered coin presses. Admiral Gardner¬†was carrying 54 tons of the copper coins, which had been destined for use by the company in India.
