Vintage Italian Cut Crystal and Silver Plate Sunburst Pattern Coasters Set of 4 The maker mark has worn off the side indicating age to me. There is a R marked in the glass on the bottom. Iv’e not been able to determine the maker of this set. No original box. Great preowned condition. I polished these up but the patina they had on them was really pretty. It was almost an oil rainbow effect. This will come back in time if that is your preference. P132
