PSA Authentication

Autograph Authentication

At Harvbo Cards we use PSA who is the largest and most trusted autograph authentication service in the world. With over 35 million collectibles certified, PSA authenticates a vast array of signatures, ranging from sports to history and entertainment. Combining decades of experience with cutting-edge authentication techniques and a passion for the hobby, PSA continues to deliver a service collectors prefer.

We can help you get your autographs authenticated from the super high end items to sentimental pieces. We do monthly submissions ranging from cut autographs to 8×10’s photos. Once a year we take items to the National Sports Collectors Convention and drop off items of bulkier size. This past year we dropped off 1,300 items and had them back by the end of the show. This is a great option to have your items authenticated and encapsulated quickly.

Autograph Encapsulation

For collectors looking to proudly display their prized autographs, and with added security, PSA offers autograph encapsulation. PSA authenticators will evaluate the autograph, and it will be encased in PSA’s sonically sealed holders – safe, secure and ready to display.
