A centuries-old variation on dice. Also called a "Teetotum," or "Ante-up" the players each ante a coin, or two, then take turns spinning the top. The side that lands facing up tells you if must "put" more into the pot, or if you can "take" coins from it. Ours is an 8-sided style, molded in resin to simulate bone. Similar tops are used for "pirate" games like "Morgan's Revengetm" Approx. 1 3/8" tall.
