Soho Mint was created by Matthew Boulton in 1788 in his Soho Manufactory (grid reference SP051890) in Handsworth, West Midlands, England. A mint was erected at the manufactory containing eight machines, to his own patent design, driven by steam engine, each capable of striking 70 to 84 coins per minute.
In addition to copper domestic coins, silver coins were made for some of the colonies, and various medals and trade tokens were struck.
After the demise of the Soho Mint some of the machinery was bought at auction, in 1850, by the new Birmingham Mint of Ralph Heaton II.
