Factual error: To reveal the invisible ink on the back of the Declaration, Ben and Dr. Chase use pure lemon juice before warming the surface. This is best seen when Chase first test it out on the corner, where the Mason symbol is placed. Lemon juice is in fact also used as invisible ink (that you have to heat to make visible), and this procedure would have ruined anything written on the back of the document.

Factual error: When Dr. Chase receives the Washington campaign button from Ben Gates, she immediately picks it up with her bare fingers and rubs it with her thumb. An expert collector would *never* handle metal objects with their bare hands like this, as the acid on the fingers will corrode the metal. Cleaning the coin afterwards is also not an option, as this presents an even higher damage risk to the coin. See http://www.stujoe.com/content/view/30/34/ for more details on this subject.
