69 Sebastiani Cab - Price?

[wink14]

Hello All - I'm new to this board. I've been keeping an old bottle and am curious about it's value.
1969 Sebastiani South Coast Counties Cabernet Sauvignon. Label says: Sturdy & Deep-Flavored. The label is yellowed with age but very clear and readble. Some fraying. Cork and seal seem perfect. No leaking. Has been kept in cool, dry cabinet, out of sunlight. Anybody have any ideas?? Thanks in advance! Wink
