Professional Sports Authenticator (PSA) is considered the gold standard when it comes to grading vintage baseball cards for their condition and authenticity. PSA began grading cards in the early 1990s and has since developed a grading scale and authentication process that is highly trusted within the hobby.

For vintage cards in particular, a PSA grading is very important because the condition of old cards can vary so greatly based on how well they were stored and cared for over many decades. PSA assigns each card a numerical grade between 1-10, with 1 being poorly preserved and 10 in pristine condition. This gives collectors a standardized way to understand the condition of a card prior to purchasing.

Perhaps even more valuable than the condition grade is PSA’s authentication. With vintage cards that are over 50 or sometimes even 100 years old, fake or altered cards do unfortunately exist. PSA features security measures like watermarks, holograms, and serial numbers on their holders to protect against counterfeits entering the marketplace. They also have experts on staff that can analyze factors like centering, printing quality, and card stock to verify a card has not been tampered with.


Obtaining a PSA authentication essentially provides a stamp of approval that the card being purchased or sold is the real thing. This gives collectors great peace of mind, especially for high value vintage cards that could be targeted by counterfeiters. PSA will also verify attributes like errors, variants, and serial numbers to confirm any significant identifying features that could impact a card’s worth.

When searching for vintage baseball cards to add to a collection, the inclusion of a PSA holder is almost always a requirement for higher end, valuable pieces. Some of the most iconic and recognizable vintage cards that are routinely slabbed by PSA include:

1909-11 T206 Honus Wagner – Considered the ‘Mona Lisa’ of sports cards. High grades can sell for millions. PSA is crucial to authenticate this card due to fakes.


1952 Topps Mickey Mantle Rookie Card – One of sports card’s true holy grails. PSA verification protects the $5-10 million value of high grade examples.

1933 Goudey Babe Ruth – An early and historic pre-war issue. PSA grades and verifies attributes like uniform/team depicted.

1916 M101-4 Babe Ruth – The Sultan of Swat’s rookie is among the earliest identifiable players. PSA experts can determine authenticity.

1914 Cracker Jack Honus Wagner – A pioneer tobacco era treasure. Requires close examination versus reprints to receive PSA backing.

1956 Topps Mickey Mantle – Captures the peak of Mantle’s career. Huge money cards in PSA 8/9+/10 condition.

1954 Topps Roberto Clemente – Iconic Pirates star’s first issued card. Need PSA certification for major investment pieces.

1913 E92 Striking Cabinets Joe Jackson – A premier pre-war card to find in high grade in certified holder.

1911 Diamond Stars Walter Johnson – Early 20th century great depicted with rare old tobacco brand. PSA verifies condition/authenticity.


While PSA slabbing does carry submission fees, using their services is strongly advisable when pursuing these crown jewels of the vintage card market. The assurance of a professional grade/authenticate far outweighs the costs, protecting both buyers and sellers in high stakes transactions of cards dating back over a century. PSA has essentially become the governing body that established collectors can trust when pursuing their most prized vintage pieces.

In further examining smaller vintage issues like tobacco cards from the 1910s or early bubblegum/toy inclusion issues of the 1950s, PSA remains the top authority. Even unlicensed regional sets and oddball local players can achieve added value with their verification. While condition has always been key, PSA authentication has given vintage collecting a level of authenticity and security previously unmatched. For the most desirable classic cardboard, their holders represent the ultimate destination for treasures passed down through generations.
