Nolan Ryan/Jerry Koosman – 1968 Topps Rookie
Just like the Pete Rose rookie card, a grade 10 copy of the 1968 combo card of Nolan Ryan and Jerry Koosman of the Mets got auctioned off. Do you want to know how rare this is? Nearly 8,000 copies of this card got submitted for professional appraisal and only one was granted this score. This explains why the card was able to go for $612,359 at the auction. A grade 9 one would go for $20,000 to $30,000.

Frank Thomas – 1990 Topps Error
During the ‘90s, the most valuable card would be the Frank Thomas one in the Topps set. This is not a regular card either but a specific error one. The card for this Hall of Famer does not come with his name on the front. This error is why it is worth a lot of money. You can expect to get something in the four or five figures for it.
