Hi there

I was wondering if you knew the age and value if any of this old Red Wing stoneware.. it is 9″ tall with a 7″ diameter.. The only marking on the jug is its stamped on the bottom Red Wing Stoneware…

Thanks Kevin


Kevin, These are safety valve jars made around 1895. There was a metal cam lever hinged to a yoke which hooked into a ridge around the neck exerted pressure on the cover, holding it down on a rubber gasket. Value would be around $50.
