Butter Crock (4 inch)

Question: {mosimage}
Hello, I have come across a very small beater jar that measures 4 inches tall and a diameter of 3 and 1/2 inches. It is marked M.S.Co. Red Wing Minn. on the bottom. It has the concave bottom on the inside. I have been unable to find this jar in any of the Red Wing reference books. Can you please tell me if this is a common piece or more on the rare side? I am going to try to send a picture for you to see. Any information would certainly be helpful. Thank you so much for your time and effort. Sincerely, T.C.

T.C. thanks for the photo as this helps me better understand your question. The photo looks like the Minnesota White High butter crocks. The 1 quart size is the most difficult to find and are valued around $100. The concave bottom however does sound like an early beater jar, but I have never heard or seen a bottom marked beater jar such as yours. You may indeed have an odd ball, but either way, I would place the value at $100 do to no decorations and the concave bottom being the only factor that would or might separate it from a white high signed butter crock.
