Mint Coining Machine - Potosí (Bolivia)

This is an old Mint Coining Machine that was powered by steam.­ It was used for minting silver coins.­

It is located in the Casa de la Moneda, the old Spanish mint where the silver from the mines of Potosí was transformed into coins.­

The original minting machines are preserved in a near-perfect state.­ The oldest machines were made of huge wooden gears and powered by slaves or animals (depending on availability).­ Later they used steam-powered machines, but luckily they kept the old machines untouched (just in case!).­ This huge building is now a national museum.­
