John Feigenbaum traveled across country to deliver one coin to an investor.

"All the way across the country I didn't sleep,'' Feigenbaum said. "I didn't eat and I didn't sleep. You wouldn't, either.''

That’s because the coin was a rare 1894-S dime. Only 24 were minted, and only nine are known to still exist. The investor in New York paid $1.9 million for the coin. Rare coin dealer Feigenbaum had to guard the coin on the trip, without looking suspicious to either Homeland Security or anyone who might want to pilfer the treasure. And he had to make sure not to spend it. Link -via Reddit
