Such a fun one, found together in Vermont along with a second vesta I've listed today, and both clearly formerly part of a larger vesta collection. This one dates to the first decade of the 20th century I believe, with the tiny dice inside the round window made of bone. I've shot the with magnification, which reveals that some of the black dots have worn away or never were, so they're not so much dice to make bets on--but to the naked eye they pass the test, as it is fun to shake them around! Looks like dark green felt behind them--nodding to the surface of a casino table. The vesta itself is either silver or nickel plated, with a hinged lid, striker along the bottom, and loop at top, such that one could wear as a pendant, which is exactly what I would do.

 2 1/2" t with loop (2 1/8" just vesta) x 1 3/8" w x 3/8" d. Good anrtique condition, general light surface wear, hinged lid opens smoothly and closes tight.
