"As far as I know, Henry was the only dealer out of 100 dealer tables offering slabbed chips for sale. "

Archie, just for the record, DeWitt Enterprises (I forget his first name) from Colorado had a single slabbed chip tucked in the corner of his sale cases. It was one of the sample slabbed chips given out for free at last year's convention. Price tag was $10, though I didn't ask him about it.
