This new 5 sen coin is made of copper, nickel and zinc, while the present coin (KM35) is made up of only copper and nickel. Both coins are silver colour. Thickness and weight for the new type are also different than before (2010 type is thinner and lighter).

I have compared a Brunei 5 sen 1994 and 5 sen 2010. The 2010 coin confirms the specifications above (weight: 1.68 g). The weight of the 1994 coin is 1.39 g. The 2010 variety is actually thicker and heavier than previous 5 sen coins, not thinner and lighter, as suggested above.
