The Greatest Muhammad Ali Autograph Resource
AliAutos.com Authentication Service
Have a Muhammad Ali autograph in your collection that you want to have authenticated? Have one you're looking to sell? More often than not, at auction, signatures that have been authenticated by reputable third parties, sell for higher prices than those without.
How it works
​
This is a physical or in-hand examination used in conjunction with the AliAutos.com Quick Opinion Service.
​
Step 1 - Fill out the Quote Request form at the bottom of this page to receive an exact price quote for your item.
Step 2 - Send a photo of your item to Shawn@AliAutos.com for a Quick Review. If your item comes back 'Most likely authentic' or if you have previously submitted the item in question, continue to step 3.
Step 3 - Send your item to AliAutos.com for the in-hand evaluation. Once your item passes the physical portion of the review, you will receive a Letter of Authenticity depicting the passed signature and it will be added to the AliAutos.com Online Database with a unique registration number that can be accessed at any time.
