It depends on the Federal Reserve District the bill was printed for. Currently, the average value of a U.S. 1976 $2 bill is about $4.00-$6.00 in uncirculated condition it is worth between $6.75-$7.00.
If you have the one from the Kansas City District, you're looking at $30.00!
If it has been in circulation: two dollars.
If it is entirely uncirculated and in pristine condition : slightly more than two dollars.
