I have a VERY, VERY OLD FITZGERALD 12 Year Old Bourbon Collector's Item Gift Set consisting of 2 glasses and a sealed 4/5 Quart Bottle of 100 Proof Very, Very Old Fitzgerald Bourbon in a green leather-like box with lock (no key). The serial number(?) is 78177679. Barreled in 1951, Bottled in 1963. What would be the value of this gift set and where would be the best place to sell it? Thanks for your help.
