Barter rings (Tagalog: panika) are ring-shaped gold ingots used as currency in the Philippines until the 16th century.
These barter rings are bigger than a doughnut in size and are made of nearly pure gold.
[1] Barter rings varies in thickness with a dual purpose: round hollow circlets of gold used as earrings or anklets by kadatuan and high-ranking nobility, aside for money.
[3] As the discovery of gold deposits were seen by the locals, the precious metal was mined and worked in the Philippines, evidenced by many Spanish accounts like one in 1586 that stated: “The people of this island (Luzon) are very skillful in their handling of gold.
The first thing they teach their children is the knowledge of gold and the weights with which they weigh it, for there is no other money among them.”[4]
