For your consideration is this fine set of 4 drink coasters of perhaps midcentury or older.
Each of these is in an elegant pressed glass starburst pattern and features a sterling silver band around the upper part.
These measure about 3 3/4″ in diameter.
They appear to be in like-new or perhaps unused NOS condition. There is some limited tarnish noted on each, but otherwise no issues are noted.
Please see the photos for more detail.
