This trade token commemorates the abolition of the slave trade in 1807. It was commissioned by Zachary Macaulay (1768-1838), the former Secretary of the Sierra Leone Company. After the Company was dissolved in 1808 Macaulay went into business on his own account, trading with West Africa. He was later joined by his nephew, Babbington.
Macaulay had had dealings with the Soho Mint in Birmingham over the production of the Sierra Leone Company's coins, so he commissioned the Mint to make his own tokens, 50,000 of which were struck.
We do not know why this design, commemorating the abolition of the slave trade, was chosen or why an Arabic translation of the text was given on the other side.
