I had that card when I was a kid and lived in Kansas City... Along with about 6-7 different Nolan Ryan cards.... Mom gave away my baseball card collection a few years after we moved back to Cali
I actually have that card as well but it would probably grade as a 6 or 7. I also have the 77 Topps set but might be missing some of them now. Reminds me of a story. I'll have to make a post about it.
