Why authenticate your collectibles?

Having your autograph or memorabilia authenticated by HSA assures genuineness and is often highly valued by both sellers and buyers.

HSA uses a proprietary based scoring system called AuthentiScore™ that provides a more transparent approach to determine if an object is genuine or not unlike traditional binary methods. 

Learn more about how our AuthentiScore™ works.
