Global sales of collectibles are on the rise, boosted by fans, young and old. And there's money to be made. Original Star Wars figures have been known to sell for $25,000, while 1959 Barbie dolls have sold for nearly as much. These days, action figures, dolls and play-sets are among the biggest sellers - as children build their collections, and adults relive their childhoods.
