Frank Thomas – 1990 Topps Error
During his MLB career, Thomas spent the majority of it with the Chicago White Sox. What did he accomplish in 19 years in baseball? Not bad, right? Two MVPs, four Silver Slugger Awards, one ML Player of the Year, one Batting Title, five All-Star Appearances, and a Hall of Fame Induction in 2014. Isn’t that nice?
The most valuable baseball card of the 1990s is the Frank Thomas mistake card from 1990. You’ll notice that his name isn’t on the card if you inspect it. This blunder now works against him, valued at around $11,000 depending on the condition, because it occurred when he was still playing.
