I found my washed up on shore from an old civil war union camp site{now underwater}. The lady that knows about these things said it was an older medicine bottle and that was the date. I would assume that he is talking about a maker or a drug but I am unsure which. She told me I could probably get about $15 or so off of it.
Need better pictures of seams on side, lip and clear pic of bottom (logo). This appears to be a blown in a mold bottle which would put it prior to 1902. Most likely late 19th century. It appears to be a 3 piece mold the bottom of which allowed the bottle maker to change out with each lot for different companies.
