Ben Franklin helped to stop counterfeiters... In the 1700s, it was pretty easy to print money that looked real. But it was Franklin who finally hit on a good idea in 1739: He cast real leaves in lead and called it the "nature print." He kept the process so secret that no one figured out how he did it until the 1960s.
