This is a S-77 misattributed as a S-76b. While they share the same obverse die, the reverse die is distinctive and identifiable. http://www.ebay.com/itm/1795-S-76b-Large-Cent-nice-/171018863027?pt=Coins_US_Individual&hash=item27d184c1b3
I see the triplet leaf at the U and the right stem, right of and even with the bottom of the A. Each is sufficient to ID the S-77 if the obverse is certain.
