1 Māṣa Java-Jenggala

Gold coinage used in the Malay archipelago between the ninth to thirteenth centuries. Presumably first developed in Java during the Jenggala period (1042-1135 AD) before spreading to various locations such as Sumatra and Malay Peninsula. Occasionally referred as piloncito due to similarities with early gold currencies used in the Philippines. Often inaccurately referred as Majapahit coin, even though common use of this coin predates the founding of Majapahit empire in 1293 AD. By the fourteenth century, cash transactions in Majapahit had actually transitioned to Chinese cash coins (Wicks 1986: 44-47, 50-55)

Early specimens resemble small, flattened, round-edged dice; later specimens are more spherical. Surviving specimens show quite consistent weight between 2.4-2.5 grams, which would correspond to māṣa unit despite the tahil inscription (Christie 1996: 250-251). These coins was part of a system used in classical Java and Bali with ideal weight and unit reconstructed as follow (Wicks 1986: 45, 59) (Christie 1996: 257-260):
1 kaṭi (608.96 g) = 16 suvarṇa / tahil
1 suvarṇa / tahil (38.06 g) = 16 māṣa
1 māṣa (2.412 g) = 4 kupang
1 kupang (0.603 g)
In Old Javanese inscriptions, these units are invariably abbreviated as ka, su/ta, mā, and ku. The latest inscription that referred to these units is from 1296 AD.
