The Third Series coins, comprising 5 denominations, were issued into circulation on 25 June 2013. The coins mark Singapore’s progress as a nation. The coin designs depict well known icons and landmarks of our nation, economy and society that Singaporeans young and old can identify easily. A common unifying symbol, the lion-head, can be found on all denominations. The new coins also have larger denomination numerals for easy identification. The obverse of the coins bears the Singapore Coat of Arms as a recognised symbol of the legal tender status of Singapore coins.
The coins are progressively sized by denomination, with the 5-cent coin being the smallest and the 1-dollar coin being the largest. Each denomination has a distinct edge pattern to help the visually impaired differentiate the coins. The surface of the 50-cent coin also has a circle of beads along the rim to enable the public to better differentiate it from the other denominations. The 1-dollar coin retains its octagonal frame.
The Third Series Coins are minted on multi-ply plated steel, comprising a steel core electroplated with three layers of metals – nickel over copper over nickel for silver-coloured coins; brass over copper over nickel for gold-coloured coins. The coins are generally lighter in weight and produce a lower pitch tone when struck against hard objects.
New security features were incorporated into the coin series, to stay ahead of counterfeiters and maintain confidence in the use of the country’s currency. The security features include a customised electromagnetic signature (EMS) for each denomination; and for the $1 coin, a bi-metallic composition (outer ring is brass-plated and inner circle is nickel-plate) and laser mark micro-engraving of the Vanda Miss Joaquim, the national flower of Singapore.
The Third Series coins were presented the finalist award for the 2013 Best New Circulation Coin or Series in the Currency Awards by the International Association of Currency Affairs (IACA). The award recognises excellence in currency issue, and was voted by IACA members comprising issuing authorities and currency suppliers such as printers and mints.

(a non-profit organisation comprising web-related professionals).
