the Chinese started coming to your state in the 1850s so I would say from mid 1850s to 1900 . I know that's a why'd spread but Chinese bottles were made very cued for a long time.
Can you do a rubbing to get an imprint of what it says?
That would help immensely.
My thoughts say 1870's, but like Sunrunner said, they can be newer and still be manufactured in a crude way.
Kudos!
