Have you ever found unknown/hidden "treasure"?
Many times I'll come across a garage sale, estate sale, etc and wonder if one of those hidden treasures lie in the piles of items for sale. For example, in recent news $2 for a folder of negatives that contained pics of Marilyn Monroe. Or a vase that ends up being a worth enough to call it a "vahz". Or maybe not as glamorous, something you found and you knew it was worth a lot and you sheepishly hand over a couple of bucks while excited on the inside then day dreaming of what you'd get on eBay (or Sotheby's).
