The Griffey was as I expected. The slice across the front also impacted the card, which is now cracked from that. What impressed me about the others was the amazing color of the cards. They really do jump out as being new, even though some are from 1970.
I would expect similar results from packs from 1970 - 1978. Wrappers from 1979 and 1980 didn't seal all of the time, so I would not expect the results to be the same. I might post some 1980 packs soon.
