Are old George Dickel whiskey bottles worth anything?

How old is your bottle? Filling level is high? Label in good condition? If you would post a photograph, it would be easier to give an estimation. But generally, old blended whiskies are not so sought...

It depends. If it's in mint condition and a collector's record then probably.

maybe if so not much

Some may have a collectors value i.e. The very first Sinclair spectrum 48k off the production line with authenticated documentation. Else to they are generally only scrap value which is low.
