I dont know if this is the most updated but Sanders makes the autograph price guide.

Just check the autograph on Ebay to see what people are actually paying for it. I have thousands of autographs but most are not worth much for a few reasons:

1. Most of my autographs are personalised which knocks the value waaay down.

2. Most of the people I have autographs of are still alive and available for someone to get their own personalised autograph of. If the celeb dies young without signing a million things it drives the value and rarity up.

3. What was the signature on? Even my older celebrity autographs are mostly on modern photos which are worth much less than vintage.

4. Besides the convention signatures and autographs I have gotten from signings I dont have pictures of my through the mail autographs. Veeeeeeeery hard to sell something for much on Ebay without photos of the signing or a certificate from a reputable company like Steiner or Creation.

bump I've been wanting to know this too, but not for selling them. Just curiosity.
