When ANTIQUES ROADSHOW cruises into Los Angeles, California, host Mark Walberg hits the beach with appraiser Gary Sohmers for a surfing collectibles safari. At the Los Angeles Convention Center, appraisers are stoked as waves of gnarly finds come rolling in, including a rare 18th-century Goanese ivory doll; a Russian porcelain charger made for the Romanov imperial family; and a circa 1785 Massachusetts shelf clock — built by Aaron Willard, brother of the renowned clockmaker Simon Willard — that has wended its way through six generations of the owner’s family, with an estimated value of $125,000 to $150,000.
