Trash or Treasure?

Nancy and her friends are helping out at a garage sale, but they're also hoping to discover some special treasures. Bess has her heart set on a ballerina painting, but right after the sale opens, it disappears. Then the girls realize there's $10 too much in the cash box -- the exact cost of the painting -- so it wasn't technically stolen after all. But Bess really wants that painting....and maybe it's worth more than $10 after all!
