Hear I have three misprint 1807 abolition of slave trade with minted errors on edge of coin, upside down writing around the edge of each coin. The minting error is around the circumference of the coin. It’s on the side of the coin in the engraving which says ‘Am I Not A Man And Brother’.
When the Queen’s head is facing upwards the writing should run along the side so you can read it, but a very small batch were released with this minting error. also dots not completed around the front facing of the Queens head on the silver part of the coin. Dots should be all the way around stops at the mouth to the neck of the Queen's head on two coins.
