Vintage Solid Brass Oversized Dice

I'm not quite sure how old these solid brass dice are but they've definitely got some good years on them, and are quite satisfying things I think, weighing nearly half a pound each, make them perfect paperweights for the desk, where one might also give them occasional toss. It appears they've been thrown around a bit, all to the good I think, and with a nice patina to the brass. 

1 1/8 cubed and in very good condition.
