The Birmingham Mint, a coining mint, originally known as Heaton's Mint or Ralph Heaton & Sons, in Birmingham, England started producing tokens and coins in 1850 as a private enterprise, separate from, but in cooperation with the Royal Mint. Its factory was situated in Icknield Street, on the edge of the Jewellery Quarter. It was created by Ralph Heaton II, using second-hand coin presses bought from the estate of Matthew Boulton.
