Harry sorry my reply might seem directed towards your response, it was not my intention to come over harsh.
My frustration is not necessarily whether the bottle has value or not but the overall concept of the definition of (rare or unique). In a lot of cases, it's overly used.
I have seen truly unique pieces dismissed on the conclusion of demand.
For Instance, there was a bottle brought to me to do some research on, as of this day I can only find one other of its like that resides in a historical museum.
Now if I was to try to garner the well-deserved classification within the world of bottle collectors of its rarity it would be like trying to part the seas because it does not fall within what's trending or mainstream and highly sought.
Yet one can find a dime a dozen on any given day what's trending or mainstream which has been classified "rare" at any show, club, antique shop, online, estate auction, etc....
