If only we knew what would become "collectable."
Things intended to be discarded but somehow escaped the trash can become pretty valuable. I saw an empty box that once held 100 primed, empty Winchester shells sell for $17,000. Only one other was known to exist.
If I had vision, I would have bought that '70 Plymouth Cuda that sold locally as just another used car in 1975. But I was newlywed and didn't have the $2600 to spare.
