1 gallon Stoneware jug follow up to Siegal, Couper question

Question:
Hello, I have a one gallon stoneware jug which i believe to be salt glazed. It is advertising Siegel,Cooper & Co. Grocery Dept.Chicago,Ill..On the bottom it is marked Minnesota Stoneware Co. Red Wing Minn. Overall it’s in excellent condition with so called turkey droppings covering a small part of the advertising wording. Please tell me about how old you think it is & does it have any meaningful value? Thanks, Tom

 

Answer: Tom, I need to know if your siegel,cooper & co grocery dept. Chicago,ill jug is a salt glazed or zinc glazed piece. This information will have an affect on it’s age and value. Please send me a photo of the front of the jug. Al Kohlman
