Stan Musial – 1948 Leaf
There are only two cards showing Stan Musial. This one is hard to find, and people like the bright colors instead of the black-and-white backdrop. In fact, Musial was a seven-time champion and memorialized into the Hall of Fame in 1969. This grade-9 card sold for $312,000 in 2018!
Goudey Lou Gehrig – 1933
Goudey Lou Gehrig actually retired in 1939, holding the record for playing the most consecutive games. While Cal Ripken, Jr. went on to break that record, a pristine condition card could go for $33,000. In fact, a grade-10 was auctioned off in 2007 for $274,950!
