What is the value of US 500 and 1000 dollar bills?

500 dollars and 1000 Dollars.

Correction. Those are the FACE values of the bills; i.e. the amount you could spend them for. But high-denomination bills haven't been printed since 1945 and are worth more to collectors so you could get more money by selling them instead of spending them. Please see the Price Guides below for more information.
