Items appraised include an ungraded 1918 $1,000 Federal Reserve note; a collection of 539 1900s stereoscopic photos and a viewfinder for viewing them; a collection of two Spider-Man comic books signed in 1991 and 1992 by writer Stan Lee, who co-created the character (a reprint of Amazing Fantasy #15 and Marvel Tales Starring Spider-Man #43), accompanied by two Spider-Man sketches signed by him, stated to be the only two sketches Lee has ever done; and a Type 89 35mm Japanese machine gun camera. When Corey questions Rick's decision to purchase the $1,000 note for $2,500, Rick makes a bet with him, agreeing to give the note to Chumlee if it turns out to be a bad purchase.
