Rick heads to New York City to check out an original broadside of the Declaration of Independence. Will he put his John Hancock on the line for this multi-million-dollar piece of history? Then, a seller jets into the shop with a rare playset based on the hit '80s film, “Top Gun.” Will Corey and Chum come out with a maverick deal, or will they crash and burn? Meanwhile, Corey kicks it with a Chelsea Football Club jersey signed by American soccer phenom, Christian Pulisic. Can he score on this deal, or will he miss his shot? And later, a seller brings in a memo written during production of “The Wizard of Oz” that leaves Chum over the rainbow —but will there be gold waiting for him at the end?
