The hobby of baseball card collecting has grown exponentially over the decades. As the popularity has increased, so too have the values of the rarest and most sought-after vintage cards. While thousands of baseball cards hold sentimental value to their owners, only a select few can claim to be among the sport’s most valuable pieces of cardboard. Let’s take a look at the 6 baseball cards that have sold for the highest prices at auction.

1909-11 T206 Honus Wagner – $6.6 million
The undisputed king of cards, the 1909-11 T206 Honus Wagner is the most valuable trading card in existence. The ultra-rare card features the legendary Pittsburgh Pirates shortstop Honus Wagner. It’s estimated only 50-200 examples exist today in varying conditions. In August 2021, a PSA NM-MT 8 example sold for a record $6.6 million through Goldin Auctions, making it the most expensive trading card ever. The card’s value stems from its rarity as Wagner demanded his card be pulled from production because he thought it targeted children towards smoking.

1952 Topps Mickey Mantle – $5.2 million
The 1952 Topps Mickey Mantle is the highest valued post-WWII card. Like the T206 Wagner, it’s incredibly rare with scientists estimating fewer than 50 PSA GEM-MT 10 quality cards exist. In January 2022, Heritage Auctions sold a PSA 10 example for $5.2 million, making it the second most expensive trading card ever. Mantle was already a rising star for the New York Yankees when this iconic rookie card was issued. His legendary career only added to the card’s prestige and demand among collectors.
