22. In Nashville, a man paid $2.48 at a thrift store for what turned out to be a rare early copy

of the Declaration of Independence, commissioned by John Quincy Adams. He sold it at auction for $477,650. The thrift store is only about a mile from my house and I have been there many times.

"Tennessean Michael Sparks strolled into the Music City Thrift Store in Nashville last year, a normal part of his weekly agenda. He picked up a candelabra, a set of salt and pepper shakers and an old copy of the U.S. Declaration of Independence. He paid $2.48 for the latter item, a "standard price" according to store manager Kay Boner.

The "standard price" was altered significantly a year later when Sparks sold the document to a Utah investment firm for $477,650, causing a national stir.


The copy happened to be one that John Quincy Adams commissioned William Stone to make in 1820. Stone finished printing 200 copies of the famous declaration in 1823. The location of only 35 of these valuable historic documents was known until Sparks punched the number up to 36 with his thrift store find.
........

Two days before Sparks' lucky find, another Tennessean possessed the article, hanging unnoticed on his wall in the garage. Stan Caffy's wife asked him to clean out the garage and ditch all the junk he'd acquired through the years. He reluctantly took the old Declaration of Independence off his garage wall and donated it, along with other odds and ends, to the thrift store. He bought it for $10 at a yard sale 10 years ago."....(more)
