All I can verify is the original work orders sitting in front of me that delivered 18,000 to a Calif.,concession co. that refused to reorder because they only sold out in 17 months at $12 to $15 each. They were not profitable enough they said, altho we only charged them .65 each in 4 colors. Now they are desired by Hard Rock Collectors even more than Chippers because they were never intended to be used on the tables (no denoms). I do not intend to explain values, supply and demand curves and all the other issues of price; but I can tell you these sell for $275-$350 and I have never had one on sale for more than two chip shows. When the brass cores all went to Dean Porter, in Denver....that was my only complete set ...red white, blue and black.
