Unless you have a bottle # in the single digits (e.g., #1-9), it's probably worth more to drink it than sell it. I have one like yours on the shelf currently, and opened another with some bourbon aficianados last fall. It's very good -- better than the middle lots (say, #s 30-90; when they began adding pot-stilled distillate after Batch 90.
Prior to Batch 90, Brown Forman simply selected the best 'honey barrels" they could find that matched the WR taste profile from their Louisville operation, finishing their aging in Woodford rackhouses. As they picked over the barrels, there were fewer and fewer 'primo' ones, and the later batches suffered.
Also, early batches were only about 8,000 bottles, while current ones run to 30,000, so there aren't as many of the very good early ones left.
