Cartwheel penny found with a metal detector for comparison
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.
