The Coining Presses during the Founding Period of the Japan Mint； Uhlhorn Münzprägemaschine and Presse Montaire de Thonnelier.

The German-made Uhlhorn coin press and the French-made Thonnelier coin press were used during the founding of the Japan Mint. These press machines were used in the final steps of manufacturing coins. Coins were made by pressing a pattern die on the front and back of circular coin material. Both presses were operated with a knee lever mechanism. These historical machines are among the few early coin presses left in the world, and have contributed to the development of press machines and the monetary system in Japan.
