Our Services

  • We provide professional autograph authentication services for collectors, dealers, and enthusiasts seeking reliable verification. Each signature is carefully examined using verified reference material, signature characteristics, and industry-accepted comparison methods to determine authenticity.

    Our evaluations focus on natural writing flow, signature consistency, ink characteristics, and known variations associated with authentic examples. This process allows us to identify genuine hand-signed autographs as well as common reproductions such as autopen, stamped, or printed signatures.

  • For authenticated items, we offer Certificates of Authenticity or written professional opinions. These documents help establish credibility, protect long-term value, and provide peace of mind for resale, insurance, or personal collections.

    Each certificate reflects the results of the evaluation and serves as independent documentation of authenticity.

  • Most autograph submissions are completed the same day, allowing collectors to receive answers quickly and confidently. More complex items or submissions with multiple signatures may require additional review time, which will always be communicated upfront.

    Eric M. - Ocala, FL

  • “About 5 years ago I looked for a reliable partner to authenticate items of my autograph and art collection. I found the service of Frank P. Garo on the web. At first I was highly skeptical, because you hear many bad things about authentication services. I decided to try his service, and received a quick and professional response, for a good price.- compared to rip-off-services like the best known company. Now, after years, I still appreciate his quick and well-founded opinions when looking for art and autographs. Mr. Garo is my first address for authentication. He helped me by saving 'tons' of money. I still use his services several times a month, I'm glad to have his professional friendship. Thank you for your work!”

    Markus Becker - Germany

  • "Frank Garo helped me with a Beatles White Album back in May which turned out to be a forgery. The really good news is that his work helped me re-coup my money back in court which was settled by a facilitator at the court before actually going in front of the judge which made things easier for all. His work was the KEY."

    Bill C. - VA

  • “…I first started using your services back in 2007-- How time flies by!! I really appreciate the honesty and integrity you bring to the authentication process. My collection is very important to me and we've seen our fair share of forgeries. I have the utmost confidence that what I have is “the real deal” and I admire the fact that you are NOT in the business of buying and selling. Please be sure that I would always recommend your services to anyone who is looking for an unbiased opinion. Thank you!"

    Greg - Allentown, PA

  • "I'm very glad that I happened to make your acquaintance and do business with you despite all of the eBay ridiculous Crap-Ola. I think your track record, experience, integrity, business value, and reputation are impeccable!"
