This seems to be a scarce embossing error. Typical nondescript aqua Hemingray No 9/ Patent May 2 1893.Not so! The patent date has an upside down and rotated 180 degrees G used instead of a 9. Front skirt is properly embossed with a 9.Photo shows the 9 on the front and the upside down G in the date. I found this in an antique shop up in Amish country in Ohio. Not listed in the 2007 PG.Has anyone submitted it for inclusion in the 11' PG that was recently released?
