Early 1900's Hellman Old crow bottle

[avilven]

I have a rare Hellman old crow whiskey bottle. There is a great blog https://pre-prowhiskeymen.blogspot.com/2016/06/the-hellmans-of-st-louis-and-battle.html That gives me the history. I am looking for a value on this bottle. I have looked for years and can find known for sale. Are they really that rare. This one is in pretty good condition with just a little staining and small hole in the label.
