Declaration of Independence: $2.4 million

The Declaration of Independence is one of the most expensive items to be sold in the 21st century. In 1991, an anonymous man decided to buy a very old photograph that had a wooden frame. It was for just $4 so he immediately took it. He bought the picture while he was on a trip to a flea market in Adamstown, PA. When he took it home, he noticed that there was something weird about the frame. He found out that there was something that was there behind the frame. When he opened the frame, he made a very surprising discovery. There was indeed another document that had been nicely kept at the back of the frame. To add to his surprise he found out that the document was actually the original copy of the Declaration of Independence. He would then sell the copy for a massive $2.4 million.
