Known as the first industrialized tool of Renaissance times, the coin mint perfected the art of coinmaking with increased accuracy over the previous hand-hammered technique. Based on Leonardo da Vinci’s genius mechanical descriptions, Michael Stewart designed and built the “drop hammer” coin mint. The "drop hammer" coin mint is operated using controlled amounts of accelerated gravity by raising a 150 lb. hammer to a height of 9 feet. The coins set between the two dies are struck with an incredible 40 tons of force! Our symbolic art reveals positive energies that may move and inspire you.
