Please help! 1989 Chateau Coudert value?

[Kcwhippet]

You have a Ch. Coudert Pelletan, and it's a decent wine, but not great. The 1989 is out there, but it appears to be hard to find outside the east coast, and I've only been able to locate it in restaurants. The current released vintage - 2000 - is going for about $30 retail. The 1989 is about $45 in restaurants.
