N/A 6 Sterling silver rimmed coasters

Vintage 1960s set of 6 Sterling silver rimmed glass coasters made in Japan, the silver needs to be polished and some may have faint flea bite chips on parts of the glass over various other minor signs of wear, but they’re all beautiful, the glass is clear and very sparkly and overall great condition no cracks and each one is marked “STERLING STC” but the writing is very faint on each one. I tried to get pictures of the markings but it’s easier to see in person and probably much easier after they’re polished
