The largest U.S. bill currently in circulation is $100, but Police in Malaysia say a Lebanese man named Elie Youssef Najem tried to pull a fast one, when he tipped a hotel worker with $500 bill. The 50-year-old, self-proclaimed billionaire, was allegedly in possession of $66 million in counterfeit currency—stacks of $1 million, $100,000 and $500 bills.

The authorities were tipped off by the hotel staff after the hotel worker he tipped tried to convert the bill into local currency. Police arrested Najem and charged him with possession of counterfeit money. If found guilty he could face up to 10 years in jail.

The U.S. Treasury Department says that $500 bills were last printed in 1945, but are no longer in circulation.
