A high price on a particular item does not necessarily mean that the object is rare. It may simply mean that there is alot of demand for that item. Case in point: A two sided error chip is rare. However, there are only a certain group of relatively few specialist collectors who have interest in these type error chips. They usually sell for a few hundred dollars each. A truly rare chip from Las Vegas or Atlantic City brings $3000 to $4000 dollars each when offered for sale because of the tremendous amount of competition from a large group of well-heeled collectors...... and/or dealers who may have clients that may be interested in purchasing such rarities. The average Joe/Jane collector can not/ will not/ spend that kind of money on a chip. As a rule, in my opinion, four figures for one chip is beyond most average collector's affordability. Similarly, a "rare" chip from Timbucktoo may not bring a high price because there are not too many collectors who collect chips from Timbucktoo. Supply & demand are key ingredients in price. Rarity stands alone by itself. I may have the only chip known to mankind. If no one else has any interest in it, it has very little value.... except perhaps to me. Archie
