"He found them mixed with other chips in an old dresser give to him to auction."

This is not the same story Roy told me.
Roy lied to a bunch of us, including a very good customer of his. I bought Roy's little baggie with the 13 UNC chips in it. Sold two of them for what I paid and free rolled on the other 11. I think I was the 2nd one to buy them, Robert E was the 1st.
He beat me by about 10 minutes at an Atlantic City antique show. BTW, Roy told both of us he only had 1 set. I found quire a few others he told the same 1 set, story to.
