I have a cylindrical-shaped stoneware crock with a lid.  The body color is an off-white. The only mark is located near the top of the crock. It is a crown in the center of which is a circle enclosing the number 20.  It is 24-inches tall and 18-inches in diameter.  I would like to sell it.  What should I charge? – RB, Big Horn, WY, Email Question

Your stoneware crock has a 20-gallon capacity, hence the number in the middle of the crown.  A previous owner must have enjoyed making sauerkraut or pickling.  Once inexpensive canned good arrived in stores, the need for 20-gallon stoneware disappeared.
