Money.
The currency in the Straits of Malacca is the Spanish dollar (ringgit or real) divided into cents. A quarter of a dollar (25 cents) is called suku (quarter). Local terms are also used to denote fractions of the dollar, as in Penang, kupang (= 10 cents), and in Malacca, wang baharu (= 2½ cents).
