A music equipment technician got the best bargain ever when he unknowingly purchased a rare, 184-year-old copy of the Declaration of Independence at a Nashville thrift shop for $2.48. However, the experts are now estimating its price at about 100,000 times the price it was bought for.

The bargain hunter - Michael Sparks, is now selling the document in an auction March 22nd at Raynors' Historical Collectible Auctions in Burlington, North Carolina. According to AP reports, he has earmarked a price of $125,000 for the opening bid but historians say there are chances it might sell for nearly twice that.

Sparks, who discovered the yellow, rolled up document last March while browsing at Music City Thrift Shop in Nashville said the clerk marked it at $2.48. After a series of online search, he found that he bargained for an "official copy" of the Declaration of Independence - one of 200 commissioned by John Quincy Adams in 1820.
