This has to be the most interesting crest & seal. For comparison purposes, the first chip is a regular no-denomination SS Tango. The second chip (third chip is the reverse of the second chip) is another ringed chip. This time USPC inlayed a real 4 leaf clover. To make sure the "customized" chip would not be mistaken for a regular Tango, the color was different, the edge was different (reeded vs square) and, of course, the ring was put on both sides.

I have to be careful about stating quantity. I was in a mistake about quantity before (One would think there was a prize...for finding error; the way some people look for it.) I do believe that both chips (blue lady chip and clover Tango chip) were special orders. I am positive that both chips were created at USPC. I've shown the chips to a couple of experts and we all agree that the chips were not tampered with. They are originals.

BTW, I do believe that the special Tango chip is the only chip that had living material inlayed into a chip.
