It seems the $2 is a star note, instead of a letter it has a * in the serial #, these are error bills and they are highly collectible if the entire sheet is like that, and if they are in good condition. If I see correctly, the date is 1976, the Bicentenial year, they should get over $1000.00 at least IMHO.

Whatever you decide on doing DO NOT CUT THEM, or give it to the young ones to play with. Protect them.
