I got this very clean Dr. Pierce’s Golden Medical Discovery yesterday for $5. I know these are not uncommon but the condition was great. Also my son just started med school at NYU and I was looking for a nice quack medicine bottle for him to display in his room. Question: what is approx date on this one, I know these were made well into the screw top era. This one has lots of bubbles, and a large vertical scar (thought it was a crack at first). The seam stops well below the double lip. Can the experts tell me please if it was a BIM type and how the lip was finished. I’m one year into this hobby now and have learned a lot but much more to go.
