Indonesia Irian Barat 50 sen President Sukarno Km-Pn4 SP62 PCGS Al coin 1965

The 1965 Indonesia Irian Barat 50 Sen Pattern KM-Pn4 aluminum coin, certified PCGS SP62, is a fascinating and scarce numismatic issue from the final years of the Irian Barat coinage program. As a pattern coin, it represents an experimental or proposed design, making it especially desirable to collectors of Indonesian patterns, rare coinage, and historical currency.

The obverse features a left-facing portrait of President Sukarno, Indonesia’s first president and one of the principal leaders of the nation’s independence movement. He is shown wearing a traditional peci cap, surrounded by the inscriptions “Presiden Republik Indonesia” and “Sukarno,” with decorative rosette symbols separating the legends. The reverse presents a bold and distinctive design with the denomination “50 sen” below the year 1965. Above the value appears a shield divided into several sections containing symbolic motifs, including a bull’s head, a banyan tree, a star, a rice-and-cotton emblem, and striped elements. Flanking the denomination are agricultural motifs: rice stalks on the left and a cotton branch with leaves and bolls on the right, symbolizing prosperity and national development.

Struck in aluminum and certified PCGS SP62, this rare KM-Pn4 pattern combines political history, national symbolism, and pattern-coin rarity. It is an outstanding addition to collections focused on Indonesia, patterns, political themes, and world numismatics.
