Hidden in the box of heirlooms were four sheets of paper, on which the writer threatened "eternal war" with England, compared the War of 1812 to the American Revolution, and lamented the downfall of Napoleon. Now, the 1815 letter written by Thomas Jefferson to then-US Ambassador to France, William Crawford, could be yours, per Fox News. Crawford’s descendants—who found the letter stashed in the attic of their Mississippi home—are selling it for $325,000. The Raab Collection, which is entertaining offers, says such a letter "comes up once in a generation," reports ABC News. (Someone just bought Jefferson's hair.)
