I purchased this set of two as vintage items about 30 years ago. I usually use D-mugs, so I only used these about once a year on special occasions. Being extra heavy, they have a substantial American presence. You can enjoy your coffee time with them. The markings on the cups are the same, but the plates are different. I don't know the special terms for vintage grading (and I don't know what this would be equivalent to), so please excuse my own explanation. Please check the markings in the photos. All of them have a gloss, but one cup has a rough area around the rim. There are also some of the characteristics of Fire King, such as the swirls in the glass. These are used items that I purchased as antiques. Please understand that they are different from new or current Fire King products, and I appreciate your understanding.
