Ancient Roman ebony dice are unusual for two reasons. First, they are carved from an exotic African black ebony wood, and second how they are marked. Typical Roman dice were marked with the same pips (dots) that we see on dice today. These however, in contrast, are marked with Roman character numerals! Seen on other gaming pieces of the period, but not typically on dice. They can be dated to the 1st Century BC/AD. - Private USA collection.
