Frank Thomas – 1990 Topps Error
Frank Thomas spent most of his MLB career with the Chicago White Sox. What does he have to show for his 19 years in baseball? Well, how about two MVPs, 4 Silver Slugger awards, one ML Player of the Year, one Batting Title, five All-Star appearances, and a Hall of Fame Induction in 2014. Not bad, right?
The 1990 Frank Thomas error card is the most valuable baseball card of the 1990s. If you look at the card, you will notice that it does not have his name on it. This is a big mistake now given his incredible career, but this mistake comes in around $11,000 in value depending on the condition.
