How much is a real 2 dollar bill worth these days?

Answer 1

As opposed to a counterfeit one?

Any modern $2 bill (dated 1976 or later) that you got in change is only worth $2 so feel free to spend it. If it's uncirculated it might retail for all of $2.50 to $4.00 but a dealer will only pay face value.
