It’s every collector’s dream: turning a modest outlay into a staggeringly high return on investment. ANTIQUES ROADSHOW “Jackpot” rolls the dice on those heady moments when luck smiles on flea market mavens and yard sale savants. Highlights include: a landscape painting acquired for $1.50 at a Salvation Army “half price” sale; a nineteenth-century album of watercolor paintings, scooped up at a yard sale for 25¢; and a 1951 Minneapolis Miller’s baseball uniform worn by Willie Mays, scored at a sports collectibles show for $50 and valued at $60,000 to $80,000.
