Tea bricks are blocks of ground tea leaves that are packed into molds and pressed. The bricks were used as a form of currency up until the beginning of WWII, when the value of tea skyrocketed in many parts of Asia.
Tea blocks were actually said to be favored over coins in places like Siberia and Tibet, as they could be used to treat coughs and colds or even eaten if food was scarce.
