That doesn't look like a pontil mark, so I still think it's from around the 1870's early 1880's like lots of torpedo sodas. Still, embossed torpedo sodas, although some are common, are usually desireable. It's sort of like Warner's Safe Cure.
Take a look at this site.

It looks like several of the topedos from the 1830s with that crude lip.
Try to contact whomever runs that website and they could probably give you some good info.
