In the earlier Foochow Pioneer days, our ancestors came from one monetary system using taels to another new system using cents.
Money was precious to the frugal Foochows and they had to learn how spend hardearned quarter cents, half cents, one cents,etc.
These were the coins they used from 1901-1950's.
My maternal grandmother said that sometimes they did not even have half cent in their pocket. And very often they had to barter trade with the Malay and Melanau fishermen who wanted salt, sugar, and cloth. My grandmother had rice which she could sell and do a bit of barter trading in the 1910's, But after the 1920's she and her growing family had rubber and that made them slightly richer.
