This incomplete 1964 Topps Giant Card Baseball Card Set (29 of 60 cards included) is from my days when I was collecting cards as a 10-year old.  Most of the cards have not been handled, and have been stored in a binder for 36+ years (in a shoe box before that).  The card characteristics that will keep most of them from being high-grades are the centering and if any have creases from the original printing.

See pictures for the 29 cards that are included. Cards that I have previously graded and sold from my baseball card collection have been graded PSA 4-6, so I would expect these cards being offered to have similar if not higher grades.  With what I know about grading, most will probably grade PSA 4-6, however some may go higher (and some lower).  I did not think it was cost efficient to pay to grade these cards, possibly with the exception of Aaron and Mantle.
Here's a breakdown of values at various grades for the set being offered which should provide some basis for my asking price:
Ungraded:  $300
PSA 4: $475
PSA 5: $640

Key cards included:  Aaron, Mantle, F. Robinson, B. Robinson, Kaline, Spahn, Killebrew, Yaz, Cepeda and Dick Stuart (common card having some value).  I also have 7 duplicate commons that I will throw in at no charge.

This set is an excellent start to completing a high-quality 1964 Topps Giant Baseball Card set - one would only need to improve the quality of  a few of those included, and acquire the ones not included.  I am also willing to send photos of cards individually to interested buyers and I would also entertain selling Mantle, Aaron and any other card separately.
