“Barry’d Treasure” follows the exploits of Barry Weiss, the eccentric collector America fell in love with on “Storage Wars.” Now retired from the storage auction game, each week he’ll embark on a cross-country journey unearthing some of the nation’s rarest and most fascinating collectibles. Riding shotgun in Barry’s enviable assortment of automobiles is his motley crew of sidekicks who aid his efforts to haggle with the toughest, and sometimes oddest, collectors in America.
