Las Vegas cab driver Gerardo Gamboa thought someone left a bag of chocolates in the back seat.
But this stash turned out to be cold hard cash.
The Las Vegas Review-Journal ( ) reports Gamboa was making a pickup Monday at the Bellagio when a hotel doorman noticed the brown paper bag and handed it to him.
At a red light the Checker Cab driver's curiosity got the best of him. To his surprise, he found six bundles of $100 bills totaling $300,000.
The newspaper reports Gamboa called his dispatcher and took the money to the company's main office.
Las Vegas police and casino officials were able to link the money to a well-known poker player they declined to identify.
It is unknown whether Gamboa will receive a big Christmas tip.
