Found ten 1976 $2 bills. How can I tell if they are worth anything

I think not over 10$

Paper money does not appriciate in value much. But in your case there were some 'misprints' that got by the inspectors. On the front, to the right of the portrait, a seal is over the denomination, as it is on all paper money. In the misprint the seal is in between the 'two' and the portrait. On the back is the signing of the Declaration of Independence. In the misprint, one of the figures is missing his face. Check them out. Misprints can be worth something. Gail

That bill is still being printed. It was stopped many years ago but then restarted in 1980. You have at least $20 face value, have them appraised
