Thanks Doug - Great stuff.
I thought this was a great analogy.
Quote:http://www.coinnews.net/2013/09/20/...circulation/the force to strike a nickel as equivalent to the impact of 3 high-speed trains, the weight of 16 elephants or the combined bite strength of 157 great white sharks. You don't really see much. The pressing action is blazing fast with up to 750 coins struck every minute.
A planchet is fed between the two and the press applies tons of pressure to transfer the designs.
35 tons for cents and dimes
50 tons for nickels
60 tons for quarters
120 tons for half-dollars
85 tons for dollar coins
