Question:
I have a 20-gal crock made by Union – although I don’t know when. The condition is very good – no chips or cracks or dings that I can see. The markings are visible on the photos. The handles are in the crock (as opposed to hanging handles).

Answer: You have a 20 gallon Minnesota Stoneware Company zinc glazed crock. Your crock was most likely manufactured between 1895 & 1906. In mint condition the value is between $200 & $250. Al Kohlman
