i have no clue
How much is Will Blackwell worth without it signed
how much is a red skelton plate worth that is signed
how much is a signed milt pappas no hit baseball worth
I have a signed print of forsythia, what is this print worth?
$300, if it is personally signed
nothing really but if it was signed by one of the characters it would be worth alot
it is worth about 10,000 dollars
A Mickey Mantle signed plaque is worth $250 - $400 depending on the size.
$0, because the stick was worth more before it was signed BECAUSE you cant prove the team signed it.
It depends what team and who signed it.
depends who signed it
