I have no idea...

Other than the 7,000 pieces of previously unknown number/color combinations that I introduced back when Stan E. made his find (they were all shipped to a woman's club in IL.. I sent Howdy shipping labels), I know nothing else about the series.

I went thru all 7,000 chips and pulled the best condition; along with the best condition overstamp denom pieces. Stan finally sold the bulk of all the remaining chips to someone.

That's all I know...
