The 1973 Topps Rookie Third Baseman card number 615 that features Ron Cey is not his rookie card. It is Mike Schmidt's rookie card and has a book value of $120.00 in near/mint condition. Ron Cey's rookie card is the 1972 Topps card number 761 -"1972 Rookie Stars"
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.
The value according to Beckett magazine is $2.00 for the 1995 Derek Jeter star Rookie #225. The important thing to keep in mind is this is not his actual rookie card with Upper Deck. His actual rookie card is the 1993 card #449 Top Rookie Prospect card (this one carries a higher value).
