Pricing on Tuscan red wine

[BamKen]

I was recently given a 1995 Luce Della Vite Toscana red wine by Frescobaldi and Mondavi bottled in Montalcino, Italy. I was told its a rare vintage and worth close to $750. Is this correct? I enjoy wine but had no idea the one I had was so expensive. Can you please help? Thank you!
