Quite interesting this - there is a seller at the moment trying to sell a 1860 TB farthing ,just an ordinary one as a mule when it quite obviously is not .
Coin is worth about £30 and he has it for sale at £1600 it would be quite easy to take him to a small claims court and claim your money back , but there again why bother when you know its only worth 2% of it BIN value .
Maybe he believe the old addage "A fool and his money are soon parted"
