#30 Large Crocks

I have two large crocks that have a blue crown with a number 30 in the crown. These have no handles, and no chips or cracks at all. I have no idea who they are made by or how much they are worth, any information would be great. Thank you

Ian, your two 30 gallon crown crocks are manufactured in Ohio. The company is still in business today and you can go to a number of local hardware stores to purchase them. By best guess on their value would be in the $50 (each) range. Al Kohlman
