Seven thousand chips were found in Florida (me) that were still in their original railway shipping cartons (I sent one shipping lebel to Howdy). They were sent to a women's club outside of Chicago, where I assume they (most) were overstamped... After cherrypicking through the 7,000 chips and taking what I needed for other collectors I walked away and lost track as to what became of the complete shipment.

There was much speculation as to their use in IL, though there were several posts by others and a well-written article by Howdy.

Archives may answer your question, exactly, as I completely lost track as to what was said, when, thereafter.
