I have twenty-three $2 bills total. All are from 1976.

All are circulated bills.
Most of them are Gs (three of the Gs have pen mark on them.
Two of them are Es (one has pen mark on it).
One is an F.
One is an L.
One is an I (it has a pen mark on it in one spot, and a black crayon mark on it in another spot).

None are star bills.
None are first-day issued.
None have low numbers.
None are consecutive.

Sorry, but they are only worth their face value. Better off to add them to a savings account and draw some interest.
