However, based on general numismatic information, the weight of a Singapore 50 cent coin depends on the series. The current Third Series coin, which has been in circulation since 2013, has a weight of 6.56 grams. This coin is made from multi-ply plated steel and features the Port of Singapore.
For comparison, the previous Second Series coin, which featured the Lion-head Goldfish and was circulated from 1985, is heavier.
