On WalletPop's Big News Podcast, Jason Cochran and I chatted up Rick Harrison, owner of the Gold and Silver pawn shop in Las Vegas, Nevada and one of the stars of the History Channel's Pawn Stars. Rick told us how his store is doing in the deep recession, tips on how to pawn your stuff, and his hottest selling items. Apparently 2,300 year old coins are common -- who knew. As for celebs in his store? Well, he's seen his share of Super Bowl rings -- what stays in Vegas has to get paid for somehow.
