Hello, thank you for the images. The 1976 $2 bill series is very common, in fact, there were 590,720,000 banknotes printed, so their value in most cases does not exceed the face value of $2 depending on the grade, condition, and current demand. What you look for in valuable 1976 $2 bills is a printing error, a star (replacement) note, or a unique or low serial number.
Unfortunately, your specimen does not have any of these features. Your bill is in overall good condition which means it is worth from $2 to $5 in the best case, the uncirculated 1976 $2 bills are worth around $10.
