The invention concerns a disc-shaped token comprising two half-discs (10, 12) in mutual contact through an axial spacing ring (14) located on the inner surface of the support half-disc (10). Said half-disc (10) has a central inner zone (28) receiving an electronic identifying device (34) and a peripheral antenna (36). The half-discs (10, 12) each comprise a central portion (21, 23) and a peripheral ring-shaped portion (20, 22) made of different types of plastic composition, the composition of the central portion (21, 23) adapted to weight the token and the composition of the ring-shaped portion (20, 22) adapted to be integral with the half-discs (10, 12) by a plastic joint (18) injected on the edge of the token in a peripheral ring-shaped zone (16) located between the two half-discs (10, 12).
