They are an early form of currency with a value that was calculated against the amount of tin by weight which could be exchanged for one Spanish Silver dollar. There are a number of views as to when the Tampang first became recognized as money, but they were likely first used in the 17th century and made until the late 19th century. Valued at 1/100 of a Spanish/Mexican 8 reales.
