How Much Is It Worth?

[havaniceday]

Hey, I have this bottle of wine and I don't really knwo how much it is worth. I have had it since 1987 and just wanted to know what you think. It's a 1987 Cabernet Sauvignon from Christine Vineyards of Glen Ellen. It's from the Sonoma Valley. It's bottled by California Wine Country, Glen Ellen, CA. The front label is of a car company, Anthony's Auto Craft. Help me out.
