I found a huge dump... huge as in the city dump from the 1820s to 1920s. It covers many many acres and you can fill semi trucks with the bottles there. I haven't dug it in over 10 years but there are tons of bottles like these. If the market ever gets good for these old bottles, I'll have to visit it more often. I used to go with a big frame hiking pack and a shovel and axe. I had so many bottles but gave most away after getting tired of being surrounded by so many old bottles. We found some straight sided coke bottles too, glass insulators, opium bottles, poison bottles, a hutchinson or two, old fruit jars, etc...
