Dear friends,
I'm doing a little research on early machine struck coins. Matthew Boulton began minting coins using steam power in the early 1790s. I've read that production of coins in the Netherlands was centralised during the Napoleonic wars, leaving Utrecht as the sole mint. I'd like to ask you this question: when did the Utrecht mint adopt an industrial mode of production, i.e. the use of steam power, striking coins in a collar, etc.?
I'd be very happy if you could help me with some information.
Vincent
