Some collectors believe that Becky Binion kept a large number of old Horseshoe chips when she lost the casino. It is very possible (likely?) that she will try to slowly leak these out a few a time to get the most she can before the values drop. Several sellers have started "finding" these very rare chips and not knowing or telling where they came from or how many there are. Pokernut is one of the busiest. For now I would treat EVERY Binions Horseshoe chip as an R-3, even the $25 Dieswirl. Prices will come down after a few people get burned.
