I don't know the value of an autographed rookie card of Darrell Green, but a regular rookie card of Darrell Green would be worth about $30.00. The worth of the autographed card would be up to the buyer of the card.
Sports card values vary greatly depending on condition. For example a Patrick Ewing rookie basketball card could have a value between $20 and $100, with autographed ones going for several hundred dollars.
If autographed, an authentic card could be worth 150.00 or more.
I would say a mint Patrick ewing rookie card would be worth about 250 dollars
UP TO 250.00
About 15-30 dollars depending on condition of the card
worth bout 750 bucks
The value of a mint condition Shaquille O'neal autographed rookie card is worth a good $60.00+
