Central motif depicts a White-browed Fantail (Rhipidura aureola), a bird native to the Indonesian archipelago, rendered in fine relief with spread tail feathers characteristic of the species. The currency abbreviation 'Rp1' appears above the bird in the upper field. The design is contained within a plain raised border, with the smooth field providing contrast to the naturalistic bird motif. |

Pattern coinage from Bank Indonesia in this period was produced experimentally as the government worked through several proposed reforms to the rupiah series. The KM#Pn4 designation with a variety notation suggests this piece differs in some recorded detail — possibly alloy ratio, edge treatment, or die alignment — from the primary pattern documented in standard references, though full variety attribution for Indonesian patterns of this era remains inconsistently cataloged across major references.
Indonesia's monetary policy in 1970 was still stabilizing following the catastrophic hyperinflation of the Sukarno years, during which the rupiah had lost the vast majority of its value before Suharto's New Order government introduced a redenominated currency in 1965.
