A treasure that is or used to be someone else's trash; for instance a piano that was forsaken that has become a treasure to someone else is a trashure.
trashsure - Any discarded object that is of dubious value could be either a piece of total crap or that missing "thing" that will finally make your life complete. To be a true trashsure, the object must be confusing as to its function or why someone would ever own the object and then throw it away in the first place.
Half Trash and Half Treasure.
