Red Wing Stoneware Crock (Salt Glaze & Birch Leaf)

What drives value

• Size is exponential: 2-gallon crocks are everywhere, 20-gallon and up get serious
• The red wing stamp must be strong — faded or missing wings cut value hard
• Early salt-glaze with cobalt decoration outprices the later white-glaze standard
• Hairlines and rim chips are the norm, so genuinely clean examples earn a premium
