A device used for reducing large prototype models down as it cuts a die. In 1899 Victor Janvier of Paris (1851-1911) invented a machine far better than previous pantographs that every mint needed. It was not the first, but the most advanced and successful die-engraving pantograph. It was introduced in the U.S. in 1907. Today�s pantograph can raise or lower a coin�s relief, flip a design so that a left facing bust faces right, and alter the slope of the field. These devices will be replaced by computer controlled cutting and milling dies.
