A movie production saddle given by John Wayne to a good friend; a diamond-encrusted gold Cartier cigarette case; and an 1856 book by famed German herbalist Mattioli.

ANTIQUES ROADSHOW circles the wagons one last time for the third and final hour of its sojourn in sunny Reno, Nevada. Host Lara Spencer and expert Brad Witherell chance upon the Liberty Belle Saloon, owned by the descendants of Charles Fey, who invented the first three-reel, automatic-payout slot machine - the Liberty Bell - the most sought-after jackpot for vintage slot machine collectors. Appraisers at the Reno Sparks Convention Center prospect for nuggets of history and find some real gems, including a movie production saddle given by John Wayne to his good friend and partner in - of all things - a catering business; a turn-of-the-century diamond-encrusted gold Cartier cigarette case, traded for three breakfasts in a small town diner; and an 1856 book, by famed German herbalist Mattioli, estimated to be worth a healthy $25,000.
