Antique Milk Glass

This was a beautiful find. My mother and grandmother collected milk glass. Im a semi expert ha ha. This piece was covered in dirt and yellow discolorwtion. It has a few splits in the handle and at the base, which are natural to the process and not actually damage after it was made. Its chunky and heavy and i love the deep harsh cut lines. I have never seen anything like this, I am not sure of its age or origin but i know its not from the 1900's. Maybe the mid 1800's or earlier. I would love to get it appraised but i dont know how or where to go.
