Plot: The Old Man hopes to hit a home run when a baseball autographed by the 1951 World Series Champion New York Yankees comes into the shop but he'll need to verify its authenticity before he steps up to the plate. Then, Rick checks out a 25-piece Knights of the Round Table set but with all the kings' men accounted for, is it really worth its weight in gold? Finally, the Pawn Stars have a chance to buy a West Point Cadet jacket owned by a famous general in 1909 - will they try it on for size, or send it to the Salvation Army?
