Cal Ripken Jr. – 1982 Topps Traded
There are a number of valuable 1982 rookie cards. However, the most valuable one would be the Cal Ripken Jr. card in the Topps Traded expansion set. The Iron Man’s card can fetch you about $200 if it is in good condition. Just be careful since the back can chip and flake. This is the reason there is such a big range of grades and prices for it.

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.
