1914 Boston Garter (Joe Jackson)
This card was meant for a window display of a clothing store, and it is thought that there are only six copies of the 1914 Boston Garter Jackson cards right now. A copy of the card with a Sportscard Guaranty 70 (the equivalent of a PSA 5.5) sold for $204,000 in August 2007. We can only imagine the value of this rare card these days. The 1914 Boston Garter Jackson is still among the most handsome baseball cards ever produced.
1954 Bowman (Mickey Mantle)
Mickey Mantle is among the most popular sports figures in history, so it should not come as a surprise that his baseball cards are extremely valuable. In 1998, Mantle was included in the list of “Baseball’s 100 Greatest Players”. That is why vintage Mantle cards with a high grade always fetch such high amounts. To prove this point, a 1954 Bowman Mantle (PSA 9) – a fourth-year Mantle – pulled in $204,000 in May 2017.
