A ROMAN GLASS GAMING DIE
Circa 2nd Century A.D.
Deep blue-green in color,
the large twenty-sided die
incised with a distinct symbol
on each of its faces
2 1/16 in. (5.2 cm.) wide
And it only went for $17,925!
I'm only a droid and not very good at telling stories.
Well, not at making them interesting, anyway.
