Astragalos

An astragalos (plural astragaloi) was a gaming piece made from the "knuckle-bone" (typically the anklebone from the hind leg) of a sheep or goat, used in antiquity in for divination and games in a manner similar to dice. Each side had a unique numerical value and, like modern dice, the values on opposite sides added up to seven. They were also used in children's games games, where players attempted to knock an opponent's knucklebones out of the center of a circle, or throw their own knucklebones in the air, catching them on the back of their hand, like jacks.

Astragaloi were often depicted on ancient Greek coins.
