Why a whale tooth could carry so much weight
In Fiji, a polished sperm-whale tooth called a tabua was not ordinary money for buying everyday goods. Its importance lay in what it could do in a consequential exchange: a tabua could accompany a marriage alliance or a peace agreement, helping mark the occasion as serious and binding.
Value in the relationship, not just the object
A tabua joined material scarcity to social meaning. A large, recognizable tooth was a tangible thing of value, but presenting one also showed that the giver was willing to commit something precious. In an exchange between powerful families or communities, that gesture could help establish trust and create an obligation to honor the relationship.
This is a different kind of economic power from a coin’s. A coin works because people commonly accept it at a set value; a tabua’s force depended on the importance of the occasion and the people exchanging it. The same object could therefore matter greatly in a treaty or marriage negotiation without serving as pocket change.
That distinction explains why a whale tooth could help seal an agreement: it was valuable enough to make the promise visible.
