Understanding the Balinese Keris and Traditional Coin: Philosophy, History, and Ritual Function

In the constellation of Nusantara culture, Bali holds a unique position where material objects and spiritual values merge seamlessly. Two of the most representative items in illustrating the depth of this philosophy are the Balinese Keris and Pis Bolong (traditional coin). Both are not merely tools of defence or exchange but manifestations of cosmic balance upheld by Balinese Hindu society for centuries.

The Balinese Keris possesses a majestic physical character. Compared to keris from other regions in Indonesia, the Balinese Keris tends to be longer and larger. Its blade (wilah) is crafted using folding forging techniques that produce pamor—metallic line patterns emerging from the mixture of iron, steel, and nickel (meteorite).

For Balinese society, the keris is a symbol of Purusha (masculine element). In religious ceremonies, the keris is often worshipped as Pajenengan or a heirloom object that protects the family or village. The presence of the keris in Balinese traditional attire is not merely an accessory but a symbol of a man’s readiness to uphold honour and truth (Dharma).

Pis Bolong, or the coin with a square hole in its centre, is tangible evidence of cultural acculturation between Bali and China that has occurred since the 7th century. This coin was originally legal tender, but over time it transformed into a vital ritual medium.

This traditional coin is believed to contain Panca Datu (five precious metals: gold, silver, copper, iron, and tin), thought to balance natural energies. Without Pis Bolong, many ceremonies in Bali are considered incomplete, from birth rituals to death ceremonies (Ngaben).

The relationship between the keris and traditional coin is often evident in high-level artworks. Some heirloom keris use Pis Bolong as part of the decoration on the warangka (scabbard) or even melted to become part of the blade’s metal mixture. The use of the coin in this context symbolises prosperity accompanying strength.

The creation of the Balinese Keris is carried out by a Pande Besi or Empu. The process involves not only technical forging skills but also spiritual practices such as fasting and selecting auspicious days (dewasa ayu). Each hammer strike is accompanied by prayers so that the keris brings safety to its owner.

Similarly with Pis Bolong. Although many counterfeit coins from zinc exist today, authentic Pis Bolong used for sacred rituals are still produced to certain metal standards to preserve their spiritual value. These coins are often strung together to form statues of deities (Rambut Sedana) as symbols of worship to God in His manifestation as the giver of sustenance.

The Balinese Keris and traditional coin are two pillars supporting the structure of Balinese culture. The Keris represents the sharpness of intellect and protection, while Pis Bolong represents the smoothness of human relations with others and God through material means. Understanding both means understanding how Balinese society values history, art, and spirituality in one harmonious breath.

For collectors and cultural enthusiasts, preserving these objects is a form of respect for the sublime Nusantara civilisation. In the modern era, the values contained within the Keris and Pis Bolong remain relevant as reminders of the importance of balance between strength and prosperity.
