As Stan Caffy prepared for married life, he and his bride-to-be cleaned out their respective garages and sold everything to Goodwill. Between the two of them, they sold an assortment of clothes, bicycles, tools, computer parts, and a tattered copy of the Declaration of Independence that had been hanging in Stan's garage for the last decade.

Stan's trash turned out to be another man's treasure.

That particular version of the Declaration of Independence was a rare copy made in 1823. A man named Michael Sparks spotted it, and he purchased the document for $2.48. Sparks later auctioned it for $477,650.

Not a bad profit.

Caffy, the previous owner, was later quoted as saying, "I'm happy for the Sparks guy. If I still had it, it would still be hanging here in the garage, and I still wouldn't know it was worth all that."
