In the premiere, store owner Robbie Sr. introduces viewers to his shop and searches for a very special Notre Dame gift for a client's husband on his birthday. Robbie is forced to buy an expensive item from an off-site dealer, hoping he can turn a profit with the client back home, knowing he risks never selling it to anyone else if she doesn't care for it. Later, a customer brings in a Cleveland Browns helmet autographed by Jim Brown himself... but is it an authentic signature? To find out, Robbie Sr. asks his friend, the football legend, to pay the shop a visit to have a look himself, and eventually Brown presides over an awkward negotiation over his own autograph. Plus, does an unsigned baseball caught by a fan over the glove of Baltimore Orioles Right Fielder Nick Markakis have any monetary value? One eager customer certainly thinks so... but does Robbie agree?
