Overview

When a customer soars into the shop with a rare H.G. Wells book, and an astronomical asking price, will Corey shoot for the stars? Next, there's no horsing around when a statue made of turquoise moseys on in. Will it be a yay, or a neigh for Rick? Then, Chum spins over to LA to have a record collection appraised. Did he scratch on this deal, or will their value be music to his ears? And finally, Rick casts his line at a vintage Plymouth 'Cuda muscle car--but will it be enough for its owner to bite?
