Well, if you have an hour, we could talk about this question of prices up or down....there really is no short answer. As you may be aware, the general antiques trade has taken a beating on prices in the past decade or longer, but bottles have mostly held there own. The key word is "mostly."
There is some softness and price declines in bottles but not nearly as much irregularity as with other antique categories. Average bottles are flat or down. Damaged bottles or mediocre examples are not doing well. Some categories have dropped while others have not. Great example and rarity are good bets but the open question is how much collectors are reaching for that great piece. In some cases, quite a bit but mostly to about average or expected selling prices. Your bottle is a bit of a tough call - I could see this doing very well at auction if two people are hungry to add this to their bitters collection. I can also imagine bidders holding back from a few bid levels because of the condition.
