Can Someone Explain This Coin To Me Please......gb 1/2 Penny

Cracked planchet, not much else to explain :)

Not a mint error at the Royal Tower of London Mint, but rather I think a quality control issue at the counterfeiter's den. This seems to be a contemporary counterfeit of George II, probably made during the time of George III. It is a brittle mixture and has developed cracks. Now if you think about mint errors then those cracks must have been in the planchette long enough for the coin to wear down to the smooth specimen we see today. It would have broken long ago if they defect came from the mint. Instead you see a shallow casting that simulates wear with a bad defect that prevented this bogus coin from circulating much at all before dropping out of the economy.
