6,000 signed index card collection from 1967-75
 

I'm consulting on the sale of a PC. The bulk of the cards are being sold at auction. The index card collection will be sold at private sales. All signatures were obtained in person.

The index card breakdown is 3,750+ pro football, 1,100+ baseball, 800 Chicago charities college football all star and 400+ misc coaches, announcers, writers and basketball. It includes multiples of all the HOF and stars players...Mantle, Mays, Aaron, Starr, Unitas. The multiples of Clemente, Lombardi and Piccolo will be sent to PSA and sold separately. The rest will be sold raw in groups of as a whole.

My question is what are the "impossible to find" or lesser known but valuable autographs? Is there an online resource or book with values? The collection has been cataloged so finding an individual name is easy.

Thank you

There are likely no "impossible to find" from this era.

There will be some scarcer ones due to the timing of their death.

Most of the common players from this era trade for very little individually.

It will take a lot of work to liquidate the collection.

Good luck in the quest.
