Message:: [QUOTE="Collecting Nut, post: 5357175, member: 74863"]This is the best information I could find. The start of the Industrial Age (late 18th - early 19th century) brought a plethora of various minting machinery which culminated when around 1830 Diedrich Uhlhorn, a German mechanic invented the coin press which bears his name. The "Uhlhorn Presse" or "toggle press" substitutes the pressure from the screw of the screw press by pressure exerted by a lever and is now exhibited at a museum. Later on, the Thonnelier press, set up in Paris in 1845, was swiftly driven by steam then by electricity. The principle of the "toggle press" which allows several hundred circulation coins to be produced per minute lives on in today's modern mechanical mint, although the pace of modern presses nowadays is extremely quick.[/QUOTE]
