Items appraised include a collection of 290 million-year-old Mazon Creek fossils of spiders and ferns, a blackjack table from the Stardust Casino, a pair of metal Coca-Cola signs from the 1950s, and a custom Down and Dirty motorcycle frame. When Rick and the Old Man learn that Corey paid a total of $18,000 to buy the frame and build a motorcycle from it, they give Corey, who entertains the notion of purchasing it himself, an ultimatum.
