1933 Goudey Lou Gehrig
It turned out that Gehrig’s popularity was just as durable as his game was on the field. In 1939, the Iron Horse retired with the baseball record for most consecutive games played at 2,130. Since then, that record had been broken by Cal Ripken Jr. All the same, a PSA 10 1933 Goudey Gehrig, which was the only one to receive the Gem Mint grade, was valued at $33,000. That was before it was auctioned off for $274,950 in 2007. Over a decade later, this is still the only 1933 Goudey Gehrig that’s been graded PSA 10.

1911 General Baking Ty Cobb
Apparently, baseball cards were sold in all kinds of things, cigarettes, candy, gum…and bread. This 1911 PSA 8 is only one example of cards that were packaged with loaves of bread. The Ty Cobb card sold for an incredible $272,980 in September 2008. In fact, it’s the highest PSA-graded 1911 General Baking Ty Cobb. The closes is a PSA 6 as of August 2018. It’s safe to say that this is one card that would make a lot of money if it were sold today.
