vintage USA stamped ceramic leaf dish

This pretty glazed piece is from around the 1960's or 70's, I believe. It is stamped on the bottom outer edge 17(6 or G) USA. It measures 11 1/2" L X 6 1/4" W X 1 1/2"-2" H. It slightly higher at the end where the stem would be. I would call the shade of green sage. It has brown speckles with white a few white starburst shapes. No damage or crazing. I can feel some roughness along the top edge in places that is probably wear to the glaze. I'm not sure if it was made to be an ashtray or just a decorative dish. Either way you can use it as you like. I ship same or next business day.
