Large USA planter console bowl, drip glaze

Very large glazed pottery console bowl or planter. It has a nice light, medium, to dark brown drip glaze. Marked (J5) hard to read(?), USA. It has a petal or shell pattern like that on a pine cone or acorn. Measures Approx 10" in diameter and is 5" deep. I thought it may be McCoy or Shawnee, but would like to know who made it for sure. Excellent condition with no damages.
