Part of Indonesia's 2016-series rupiah coinage, which replaced the previous circulation types under Bank Indonesia's currency renewal program — a wholesale reissue driven partly by counterfeiting concerns and partly by the degraded state of coins that had been circulating since the 1990s. The Semanotus russicus featured here is a longhorn beetle found across parts of Asia, slotted into a broader conservation theme running through the series that assigned endemic and regionally significant fauna to denominations.
The brass composition was a deliberate cost-control choice; earlier high-denomination rupiah coins had used bimetallic or aluminium-bronze formats that proved expensive at scale.
