I picked this one up for a few bucks.
I rarely touch jars as I know nothing on them, but I hadn't heard of this one before and thought the embossing/colour might be good.
The base also told me it wasn't exactly brand new.
All jars I see seem to have a Ball lid on them. Never figured out why.
That is a 1920 - 30 vintage jar. The BALL lids are found on them and other jars commonly as they were readily available for resealing the jars when canning.

I have one of these Wan-Eta Cocoa jars. It had to be one of the first bottles I acquired -- 1977. It is machine finished (no lip grinding). The re-usable jar must have been an inducement to buy a luxury item like cocoa during rough economic times.
