But what I'm after is to understand why the grease within the recesses of the die doesn't just get displaced and then "splash out" under all the tons of pressure during the strike. When I think of grease-filled dies, I envision putting one ice cube tray over another one which is filled. Then the water in the lower tray would just get displaced. Why doesn't that happen to the grease in the die during the minting process? I've viewed numerous videos on the minting process, but none goes into that part in detail. Thanks for your help.
