What's the value of a 1776 two dollar bill

Are there any that is worth more than two dollars

Not much. Look on ebay.

Varies a lot - again, look on ebay.
Beware though. Counterfeiting was far more common then than now, and there are ceremonial reissues too.

I would be very suspicious of the authenticity of a 1776 2 dollar bill. Who issued the bill?

I believe every conceivable denomination and fraction was issued. They were called Continentals.

Post a picture. My guess is that is a commemorative note, not a real one. Where did you get it? Any provenance?
