Value of this '89 Cab Sauv ?

[hheynow]

I'm new to this board and have a question about the value of the following wine. It's a 1989 magnum of Woodbridge/Robert Mondavi Cabernet Sauvignon. I will be donating two magnum bottles of it to a silent auction and have no idea of their value. If any of you know of any links that will help me determine their value, please let me know. BTW, the auction will be on October 9th. Thanks.
