I have a jug, it's 17" around at the biggest part, 4' diameter on the
bottom and stands about 5-3/4" tall. it has a little spout offset on
the top and a bung with a lip on it all the way around. it looks
crudely made with a spot on the side that has no glazing on it. color
is lite brown. on the bottom the markings look to be china or japan,
there is a total of 7 marks clumped together in the center of the
bottom. it also has a seam running all the way around in in the center
of the jug. any idea where it is from? or how much in may be worth?

If you could provide a photo of the jug it would help immensely.

Here is a recommendation by Researcher Politicalguru-ga from another question:

"Mindy - there are sites, where you can upload a picture of your
painting for free :

It might help if you uploaded the file and told us where to find it."
