The Boston Red Sox are one of the most storied franchises in Major League Baseball, having won 9 World Series championships since joining the American League in 1901. With over a century of history and some of the game’s all-time greatest players suiting up in the iconic red socks, there is no shortage of amazing baseball cards featuring Red Sox players through the decades. Here are some of the best and most valuable Red Sox cards collectors should keep an eye out for:

1912 Nap Lajoie T206 – One of the earliest and most iconic baseball card sets ever produced was the legendary 1909-1911 T206 set.

Graded mint condition examples of Lajoie’s Red Sox T206 card in a PSA 8 or higher can fetch over $50,000 at auction.
