Referring to the make up of the diamond suit on these chips. You'll notice on my picture the diamond is made up of two "L" shapes, not connected, with the left on top, but if you follow the link and look at the same chip it has the right on top.

I have found Robert Eisenstadt's web site to be very helpful on mold designs. http://www.antiquegamblingchips.com/molddesign_suits.htm#md36c
