Hub & Die Process B-Roll

This B-Roll begins with the process of making "hubs," which is done by CNC (computer numerically controlled) machines using cutting tools. Once a master hub is machined, the Mint uses it to create dies, which have negative images of the coin's front or back, and will be used to strike the coin. Coin presses use 35-100 tons of pressure (depending on denomination of the coin) to leave the final impression on the coin.
