THE “DROP HAMMER” COIN MINT was based on Leonardo da Vinci’s mechanical genius. It was the first industrialized tool of Renaissance times, perfecting the art of coin-making with increased accuracy over the previous hand-hammered techniques. The 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!
