1989 Upper Deck Rookie (Ken Griffey Jr.)
This is the most important and probably the most recognizable rookie card of Ken Griffey Jr., one of the greatest all-around baseball players in history. Across the 1990s, many people believed that this 1989 Upper Deck rookie card would become one of the priciest baseball cards of all time. This may not have come true, but the card is among the most iconic in the past three decades. You can expect to get $400 for one that has a good grade. However, like many Griffey rookie Cards, it is subject to a hidden flaw – the reverse side has a factory wrinkle.

1952 Topps (Willie Mays)
In addition to the famous Mantle card, another valuable card that is part of the 1952 Topps set is the one featuring New York center fielder Willie Mays. The Hall of Famer is arguably the best centerfielder the MLB has ever seen. He is usually best remembered for “The Catch”, an incredible play that he made during the World Series in 1954. The card of the Yankees slugger may be more valuable than the 1952 Topps Willie Mays, but the card of the Say Hey Kid fetched $478,000 at an auction in 2016.
