I have about 175 cards from 1976 Topps football. Of those, about 30 are awful (badly creased, torn corners).
About 30 I would say are decent (no visible crease, minor corner damage). Here are some examples of those:

Quite a few others are a little worse than those (corners more damaged but no visible or light creasing)

or are off-centered or minor visible creasing:

Then others are badly creased:

These are just representative samples. I can send more photos if you like or can search for cards that you need among the 140 or so cards and photo the ones you need to see if you'd like them. Or I can send you numbers of cards I have.
Let me know what you think. If you end up needing some I have, I am really not going to be looking for anything other than 1-2 baseball inserts in return.
