Couple weeks ago I found an old bottle in the woods across the street. Made in March of '48 according to the bottom, by the Cope Bottling Company of Taunton MA. Apparently they're out of business now and the bottle is worth like $5. Thick glass, some weird petina like stuff on the inside, possibly residue from all the dirt that was inside, or maybe from all the soap I used to try to clean it.
