The Christian Brothers Champagne Brut 1964

[Marianne1982]

    Hello,

I found a bottle of "the christian brothers california champagne-brut at a yardsale from 1964 as it appears...
I would really like to know if this is worth anything ? (I am not a collector but thought this might be an interesting piece)
The champagne seems to still be bubbly as it does not have any kind of trash in it (corroded cork etc.)

I am not sure if this is the right thread to ask about this,if not so, i am sorry !

Thanks for any answer in advance
