At Quarterdeck Collectibles, authenticity is not optional — it is foundational. 
 

We understand that serious collectors and investors require more than enthusiasm for memorabilia; they require verification, documentation, and confidence.  Our commitment is simple: every item we offer is represented honestly, vetted carefully, and supported by credible authentication whenever applicable.

If you have questions about authentication, certification numbers, or verification methods, we are always available to discuss the details. We believe direct communication builds lasting trust — and trust is the most valuable asset in collecting.

Authentication
 

The “Cardboard Connection” authored an article on autographs and the authentication of those items that we feel are extremely accurate and important for everyone to know.  The highlights of the article are cited below:

It should be stated that autograph authentication is one of the most controversial and murky aspects of collecting sports memorabilia. The methods employed are far from an exact science. Most reputable authenticators, themselves, will admit that even under the best circumstances, their findings are merely an opinion. It is not concrete proof of a genuine autograph. 

Quite simply, the only way to ensure that the autographs in your collection are authentic is to acquire them in person. This process includes handing the item to the athlete, watching them sign it, and having the athlete hand the item back to you. That being said, there are probably items already in your collection that you would like to have authenticated. However, once you make that decision, be prepared for potential disappointment in the results.

The Autograph Authentication Process

There are literally dozens of autograph authentication companies in existence today. From forensic document examiners to so-called handwriting experts, to corporate institutions like PSA/DNA and others that claim to use state-of-the-art technology with fancy-sounding names like Color Spectral Deconvolution or Video Spectral Comparator, the autograph authentication choices available to a collector can get confusing.

Regardless of the company, all autograph authenticators use some form of a multi-step process that includes examination and analysis of the ink and medium, object evaluation, side-by-side signature comparison, structural analysis, tagging and certifying.

All autograph authentication starts with the following examination:

  • Ink/Medium Analysis
  • Object Evaluation
  • Structural Analysis
  • Side-by-Side Comparison
  • After Evaluation
  • Tagging
  • Certifying
  • Specialized Autograph Authentication Tools
  • Color Spectral Deconvolution
  • Video Spectral Comparator Analysis

Autograph Authentication Companies

As previously mentioned, there is a range of companies to choose from. A simple online search will reveal many that fall outside of what the hobby has established as reputable. In reality, even these companies have been known to make their share of mistakes given the nature of the authentication as just an opinion in the first place. Couple this with the fact that autograph authentication is a for-profit business and you can imagine the potential issue that may result.

Autograph Authentication Pitfalls

One of the most troubling things collectors encounter from time-to-time is when they submit an autograph for authentication that they have acquired in person, only to have it rejected by the authenticating company. What recourse do you have as a collector if this happens? Unfortunately, there is very little that can be done.

As frustrating as this can be, your only options are to submit the item to another authenticator or simply be satisfied in knowing for yourself that it is genuine. While this may help when the item resides in your own collection, it certainly will make it difficult to sell the item in the future without a reputable LOA.

We state all of the above for informational purposes, but in the end, you need to feel comfortable with your purchase.  If you have any concerns or questions about authenticity, please reach out.  We’re here to help.
