I have a chance to buy 26 1980 Topps Baseball 3 card cello packs that were part of a promotional deal by Mrs. Butterworths Syrup for $25 so thats 78 total cards, all the packs are in mint and have the Mrs. Butterworth promotional card on back. The lady has had them for over 30 years she used to work for the company my question is should I jump on them? I mean that chance for a mint Rickey Henderson Rc! or do I buy them and sell them as individual packs on ebay? Just wanting some opinions......
