9. The death penalty dollar

The U.S. dollar has grown into one of the world's most stable currencies, but that wasn't always the case. In fact, before it could grow in value, it had to rein in counterfeiting.

"When the colonies first started, it was pretty easy to print; there were a lot of printers, money wasn't very sophisticated and there just wasn't a lot of anti-counterfeiting," Doty explains. "So how to you create artificial scarcity? You print on the money, ‘To counterfeit is death.' All 13 colonies printed this on all of their money, which was eventually replaced by ‘In God We Trust.' Before we had ‘In God We Trust,' it was actually in the death penalty we trust."
