Movable goods which may be estimated and replaced according to weight, measure, and number. Things belonging to a class, which do not have to be dealt with in specie.
Those things one specimen of which is as good as another, as is the case with half-crowns, or pounds of rice of the same quality. Horses, slaves, and so forth, are non-fungible things, because they differ individually in value, and cannot be exchanged indifferently one for another. Holl. Jur. 88.
Where a thing which is the subject of an obligation (which one man is bound to deliver to another) must be delivered in specie, the thing is not fungible; that very individual thing, and not another thing of the same or another class, In lieu of it must be delivered. Where the subject of the obligation is a thing of a given class, the thing is said to be fungible; i.e., the delivery of any object which answers to the generic description will satisfy the terms of the obligation. Aust Jur. 483, 484.
