Brien,
I have no reason to doubt the sellers story.
But, if 3 other sellers put up the same auction with the same story, how would you discern which one was telling the truth and which ones were not.
Or what if they put up the same chips with a different story, who could you believe?
Generics were sold to anyone and everybody that would buy them.

Like Travis I have generics I know were used in illegal casinos. If I tried to sell them to you, you could only take by word for it.
