How could this get authenticated?

and forgers take advantage of that fact.

What's amazing is Ali has probably signed more legitimate autographs then Bob Feller, and the forgeries still probably outnumber the real sigs, about 20-1.

Bergin and Tinkers hit it on the head, even though I would think that Feller has signed more as he's across the street right now signing for loose change, but people still feel the need to forge the champ. The day he passes, there could be 100,000 signatures on eBay and probably 80,000 of those will be fake. It will be an immense prison break.
