Earle42 Bedrock of the Community United States 10038 Posts	Posted 11/04/2021 11:14 pm Tons of pressure and very fast movement of metal, dies, and planchet make for happenings our normal life experiences say should not. The die is bouncing after the strike and impacts the coin which has just had uniform tons of pressure lifted off of its surface a micro second before the bounce. The die catches certain areas responding from tons of pressure release and plows/pushes metal out of the way. I would assume as the edge of a device's design in the die impacts the coin's surface, the coin can move somewhat out of the way, but a limitation comes from a physical obstruction. The coin movement stops, and the plowing plowing occurs. Since the die is loose and therefore at an angle to the coin's surface, the plowing is not uniform across the entire surface. All theory. How much squash could a Sasquatch squash if a Sasquatch would squash squash?
