About ASM
ASM, the renowned provider of autograph authentication services, was established in 1998 to combat the proliferation of counterfeit, forged, and pirated signed collectibles. ASM's innovative grading system has revolutionized the way in which collectibles are valued, traded, and enjoyed, and its four-tier authentication process has greatly enhanced the hobby of autograph and memorabilia collecting. Over the years, ASM has authenticated countless autographs and collectibles from the realms of sports, music, entertainment, politics, and history, including some of the most valuable specimens in existence.
Why Choose ASM
In an industry where counterfeiting and forged autographs run rampant, it is near impossible to sell an autographed item without third-party certification. Buyers know they can't just take the sellers word that they got the item themselves, and sellers know that they can increase the value of their item by having it authenticated. But which company does the authentication matters, not all third party experts are equal.
Authentic Sports Memorabilia led by Jason Bell and Vinay Das, have a combined 25 years of experience authenticating autographs. It's not just that they have been doing this longer than everyone else, it's that they are responsible for personally authenticating the most valuable items in the industry including: Babe Ruth's 1918 contract with the Boston Red Sox, the 1857 Laws of Baseball document and the only known Joe Jackson signed photograph. When there is an item of significant value that needs authentication, the industry turns to Bell and Das for their expert opinions.
More than just our experts being the best, ASM utilizes cutting edge technology to add security features to all of our products to prevent counterfeiting. Our tamper-evident encapsulation holders are impossible to penetrate without detection, which means once it has been hermetically sealed, you can rest assured that you are receiving an authentic ASM certified item. Our certification stickers can only be applied to an object once, and if someone does try to remove it, it will be evident. Everything we do, from our online database to custom watermarked paper, is to protect you, the buyers and sellers of ASM.
