I voted for "Any" but when I viewed the results, I changed my vote to "Any". Then I changed my mind and withdrew my vote. Chris
With a hammer one good lick will do it. In that video, did you notice how fast the coin can be milled out or flat. And once you get the right setting a stop can be set and you can mill one coin after another to the same precision as fast as you can set them up. Getting the precision of the initial setting could take some time, but once you have it set you can probably crank out a couple dozen of these an hour.
Yep. He had those settings down. Once he removed the rim from the quarter, it was a nice tight fit inside that golden dollar.
