Behind the Scenes of Autograph Authentication: How We Ensure the Legitimacy of Our Products

At Autograph Pros, we take pride in offering authentic autographs to our customers. But what exactly goes into ensuring the legitimacy of our products? In this blog post, we'll take a deep dive into the world of autograph authentication and uncover the techniques and processes that make it possible.

What is autograph authentication?

Before we delve into the authentication process, let's define what we mean by "autograph authentication." Simply put, it's the process of verifying the authenticity of a signature or autograph. This is important because the value of an autograph can vary widely depending on its authenticity. For example, a signed baseball from Babe Ruth is worth a lot more than a signed baseball from someone pretending to be Babe Ruth. This is where authentication comes in - it provides peace of mind to buyers and sellers that their autographs are genuine.

But autograph authentication isn't just important for buyers and sellers - it's also important for the integrity of the autograph collecting industry as a whole. Authenticators serve as gatekeepers, ensuring that fake autographs don't flood the market and devalue the genuine ones.

The autograph authentication process

So how exactly do authenticators go about verifying the legitimacy of an autograph? It's a multi-step process that typically includes research, physical examination, and comparison to known authentic examples.

Step 1: Research and analysis

The first step in the authentication process is research. This involves gathering as much information as possible about the autograph and the context in which it was signed. For example, was the autograph obtained in person, or was it purchased from a dealer? Where and when was it signed? Is this a vintage style signature on a modern item?  All of these factors can impact the authenticity of the autograph, so it's important for authenticators to have a complete understanding of the autograph's history before moving on to the next step.

Step 2: Physical examination

Once the research is complete, the autograph is subjected to a physical examination. This involves looking at the autograph under magnification to examine the individual strokes and pressure points. Authenticators will also look for telltale signs of forgery, such as traced or stamped signatures, facsimile/preprint signatures, and autopens. In some cases, the ink or paper may be subjected to scientific analysis to determine its age.

Step 3: Comparison to known authentic examples

If the autograph passes the physical examination, it's then compared to known authentic examples. Authenticators will use their expertise to compare the autograph to other examples from the same time period and/or signed by the same person. If there are any discrepancies, further analysis may be necessary to determine whether the autograph is genuine.

Step 4: Finalizing the authentication

Assuming the autograph passes all of the previous steps, the authentication is finalized. The autograph is given a unique identifier and a certificate of authenticity is issued. This certificate serves as proof that the autograph has been authenticated and is genuine.

Common misconceptions about autograph authentication

Despite the importance of autograph authentication, there are several common misconceptions about it. Let's take a look at a few of them:

Myth 1: All authentication services are the same

Not all autograph authentication services are created equal. Some are more rigorous than others, and some have a better track record of catching forgeries. Some put in the extra effort to combat fraud such as putting photos of the items authenticated online so that fake stickers and COA cards can’t be produced and used with forgeries.  Some definitely have specific areas of expertise while others try to be all things to all people.  It's important for buyers and sellers to do their research and choose a reputable authentication service.

Myth 2: Autograph authentication is 100% foolproof

While autograph authentication is an important tool for verifying the legitimacy of autographs, it's not foolproof. There will always be forgers who are able to replicate signatures with a high degree of accuracy. That's why it's important to work with a reputable authentication service and to be vigilant when buying autographs.

Myth 3: Autograph authentication is only necessary for expensive items

While it's true that the value of an autograph typically increases with its rarity and historical significance, that doesn't mean that less expensive autographs don't need to be authenticated. Even if an autograph is only worth a few hundred dollars, it's still important to ensure that it's genuine.


Autograph authentication is a complex and important process that serves as a safeguard for both buyers and sellers. By following a rigorous authentication process and being transparent about their methods, authenticators are able to ensure the legitimacy of autographs and protect the integrity of the autograph collecting industry.
