How much is an Earl Anthony signature worth?

I have a signature of Earl Anthony's that is 100% authentic, on the back of a score sheet from a ProAm tournament. I researched it somewhat, and found one worth $250 which was a photo of him and signature, the other was worth $600 which was from Classic Cuts/Upper Deck, that was just his signature on a card. |||Those he signed all the time


they are more of a personnel value than anything


i have a personalized autograph of him


and also so does my brother even more personalized and so does my sister





it maybe worth a few bucks but if it is in a yearbook type it may be worth a bit more
