You've seen this set complete before. You've seen the unopened, single card packs , made of paper so thin you can easily see the card inside. Have you ever seen a complete set of all 54 cards still in the unopened packs? We hadn't until this one came through the door. The 5 packs we had graded were:
Tom Seaver HOF PSA 9
Reggie Jackson HOF PSA 9
Pete Rose PSA 8
Roberto Clemente HOF PSA 8
Bob Gibson HOF PSA 7
Of course those grades are for the pack, which, while thin, are not see through enough to evaluate card condition. We didn't grade the Willie Mays pack because it has writing in red marker on it (which shouldn't affect the card inside). You may have to wait a long time to see the set offered in this way again.
