Plaster Model of Dwight D. Eisenhower Dollar

Description (Brief)
When Gasparro was satisfied with his drawing for a new coin, he produced a version of the drawing in clay. Next, a plaster model, or galvano, was made using the clay version as a mold. When the Dwight D. Eisenhower dollar was manufactured in 1971, the Mint engraver used a plaster model on a lathe to scale the design down to coin size and reproduce the image onto a master hub. Today artists may still make plaster galvanoes to demonstrate their coin design in three dimensions, but the manufacture of the hub is done with computers. Images are scanned onto a computer, and software reduces the object and carves the hub.
