mod vintage solid brass leaves coaster set, leaf shaped drinks coasters or ashtrays

Set of four vintage solid brass leaves, which stack neatly for storage. These work perfectly as coasters as you can see (glassware not included). But I think they'd also make great ashtrays, they're nice and heavy, and burn proof!

They measure 2 1/2" across the center (the area for the glass). There's some tarnishing from age and use, though I'm uncertain as to their exact age. Mark on the back is simply J T P.
