Officials of the American Savings Bank in Munster, Indiana, say a woman deposited two crisp $1,000 dollar bills.
Bank president Michael Mellon says they called the customer to have her take the bills back.
It's not that they were fake, but are worth a lot more than the face value.
A rare coin dealer says the bills could be worth up to $4,500 each.
Mellon says they're just looking out for their customer. The bills were issued in 1934 and have been out of circulation for decades.
The woman told bank officials they had come from a relative years ago.
