Han's dice were a pair of gold dice owned by the smuggler Han Solo.

Han Solo won the Millennium Falcon from Lando Calrissian with those dice. He kept them as a lucky charm and hung them in the cockpit of the Millennium Falcon.
Shortly after the Battle of Endor, Solo inspected the Millennium Falcon to reacquaint himself with his ship. During his inspection, he found the dice still hanging in the cockpit, just the way he left them.
These dice only appear in one scene of Star Wars: Episode IV A New Hope. They are not seen again in the rest of the original trilogy.
