Question:
we have a 15 gallon 4 birch leaf crock in mint condition,also a three gallon water cooler says red wing in the oval also i believe it says potteries inc.coul you giv me info and value both pices ar in mint condition Chris

Answer: Chris, a 15 gallon birch leaf crock would have been produced between 1895 & 1909. It could have been made by the Red Wing or the Minnesota Stoneware Company. You did not give me enough information to tell the difference. Either way the value in perfect condition is between $200 & $250. Your 3 gallon Red Wing water cooler with the potteries oval was made between 1936 & 1947. In perfect condition and without the lid, $250 to $300. Al Kohlman
