What is the value of a 1976 Hawaiian dollar?
There's no 1976 US dollar coin with any specific connection to
Hawaii, and no $1 bills have that date, only $2 bills. Both carry
designs for the Bicentennial celebration.
You may have something made locally for the Bicentennial, or an
older bill from WWII that had the name HAWAII on the back. Please
check again and post a new, separate question with more
information.
