No idea on the value personally, and I'm really still getting my bearings with identifying old bottles. I can tell you this is one of the coolest bottles I've seen(personally) posted in a while! I love a good old whiskey bottle anytime! Absolute great recovery! If it is 1880s as was stated I always can hardly believe glass can lay around that long and not get broken, lol. It happens though for sure, you have proof(as do I)! I hope it is worth $9k that would be amazing to say the least. I'd look into that for sure. Could be somebody poking fun(not accusing the poster of that, but it's hard too tell sometimes, lol), but more likely it's a real quote from a bottle reference book and it may well be correct. $9k is nothing to sneeze at for anybody! Love the look of it though either way, I'd love to find something similar sometime! May be even the 13th and 14th known to exist if the above post IS correct! There are certainly bottles found all the time with only a few known EXISTING examples, even new unidentified bottles popping up out of dumps etc. I hope this is a valuable find, very cool either way though. It's funny because I randomly have a bottle I found today I'm about to post right now, and your bottle post was top of the list on today's finds, lol! you ought to come check my bottle out too! Nowhere near as bad@$$ as yours though for sure lol. I'd check all around the area you found the bottle, could have been a brand loyal drinker lol. Good luck, happy and safe hunting!
