Not many ABM bottles are sought after with a few exceptions. Safe Bottle is a good example of a bottle which is attractive, old, and for sake of argument, say its perfect. The one thing it is missing is rarity. At the same time, there are wonderful variants and colors in the Warners family of bottles which are quite rare, and can bring very big money. The scarceness is key to determining in the value in Warners.
Final thought is about bottle prices in general.
Seems to me like the hobby is really taking off lately. Auction prices are higher than ever, and a number of antique shop owners in my area have said that bottles are selling well. They used to sit around forever, but now they are being snapped up as soon as they go on the shelf. I ve read where some folks are bothered by higher bottle prices. I m not bothered in the least.
