| Additional information |
Indonesia's long-running fauna series has used coinage as a vehicle for species awareness since the 1990s, and the ground beetle Calosoma sycophanta is an unusual choice — it is not native to the Indonesian archipelago but is widely distributed across Europe and Central Asia, where it was deliberately introduced to North America in 1905 to combat gypsy moth infestations. Whether its inclusion reflects a conservation message or a cataloging error in the series planning has never been officially clarified by Bank Indonesia.
