Don't think there were coal mines, we used to make things but Sheffield is more synonymous with the steel industry, we're cars, guns and jewellery.
True. Merry Hill sits on top of a massive abandoned coal mine (but of course, not in Birmingham) Here is what I found on Birmingham: brass and iron founding, saddlery, military accoutrements, fire-arms, swords, and cutlery of various kinds; jewellery; gold, silver, plated, and japanned goods; buttons; medals; gilt, silver, ivory, bone, and other toys; glass; wood-turnery; metalrolling; tools and implements of all kinds; mills; machinery of all sorts; and steam-engines on every known principle. Casting, modelling, die-sinking, engraving, and other processes connected with the various manufactures, have likewise been brought to the greatest perfection; also the cutting of glass link
