Ivy will look into converting the VISIO files to CAD drawing and having dies milled on CNC machine.  Extensive calculations determined that the 1-Troy-ounce credit-card shaped pieces will need to have a seperate die size for each alloy, whereas the square 10 g pieces can be made with the same die but with different sheet thicknesses.  Current prototype measurements and weights are as follows:

48 mm x 77.66 mm @ 20 gauge Sterling = 31.1001 g 

38.9 mm 22 ga square = 10.0855 g Fine vs. 9.9605 g Sterling

Re: 1/21/08 Minutes and Die details

One very important detail is missing here: what is the radius of the corners?

Also, can someone attach the Visio drawing? Other formats could be nice as well.
