Quart size Mason Jar of 1872 ground lip. Can't find any that are like this and wondering potential value. I did find a pint size that was sold for $225.
Sorry for the sideways pic.
I believe that is #1749 jar in the redbook. It lists for 50-75 dollars but that is with the closure. Closure value: 40-50% (pint size is higher value) Nice jar. (Base is unmarked and nothing on the back I assume?)
