Circulation Currency: Coins

View details of the current Third Series of coins as well as past circulation coins.

Third Series (2013 - Present)

The Third Series coins, comprising five 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.

To facilitate identification by the visually-impaired, the following features have been incorporated:

  • Progressive sizing by denomination, with the 5-cent coin being the smallest and 1-dollar coin being the largest, to allow users to recognise the coins more intuitively.
  • Tactile features such as the different edge patterns on each denomination of the new coins: micro scalloped edge pattern for the 50-cent, milled edging for the 1-dollar and 20-cent, interrupted milled edge pattern for the 10-cent, and plain edging for the 5-cent.
  • Higher relief at the rim of the 1-dollar coin; the 1-dollar coin retains its octagonal frame.
  • A circle of beads along the rim of the 50-cent coin.

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 (i.e. 10-cent, 20-cent, 50-cent and the inner circle of the 1-dollar coin); brass over copper over nickel for gold-coloured coins (i.e. 5-cent and the outer ring of the 1-dollar coin). As with all copper-based materials, brass will lose its shine when it oxidises. Oxidation is a natural process and the rate at which the coin oxidises depends on its handling and the elements it has been exposed to.

The tarnishing of the coin does not diminish its value or change its electromagnetic signature (used by most coin-operated machines to identify and authenticate coins). They will continue to be accepted at banks and automated coin handling machines. Coins that are unfit for recirculation will be removed.

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-plated) 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.

The Third Series micro-site was awarded the “Best in Class – Banking category” in the 2013 Interactive Media Awards (IMA), organised by the Interactive Media Council Inc. (a non-profit organisation comprising web-related professionals). The Best in Class award is the highest honour in the IMA and represents the highest standards of professionalism, standards compliance and planning and execution in website design and development.

Second Series (1985 - 2013)

The Second Series of circulation coins bear the Flora theme and feature local plants and flowers. It is aimed at enhancing Singapore's image as a garden city. Four denominations, namely the 5-cent, 10-cent, 20-cent and 50-cent coins, were the first to make their appearance on 2 December 1985, followed by the 1-cent and 1-dollar coins on 28 September 1987.

The obverse design of the coins bears the Singapore Arms in the centre surrounded by the word "SINGAPORE" in the four official languages (English, Malay, Mandarin and Tamil) around the circumference of the coins. The year-date is below the Singapore Arms. In addition, a ring of dashes surrounds the Singapore Arms on both the 10-cent and 50-cent coins. There is an octagonal frame around the circumference of the 1-dollar coin; its milled edge bears the inscription "REPUBLIC OF SINGAPORE" and a lion symbol. Since 28 May 1990, the 50-cent coin has been minted with a plain edge with the inscription "REPUBLIC OF SINGAPORE" and a lion symbol.

Denominations

There are six denominations in the Second Series.

Note: MAS stopped issuing the 1-cent coin from 1 April 2002 as the denomination was not actively used by the public. 1-cent coins that are already in circulation remain legal tender in Singapore. MAS has not demonetised the 1-cent coin so that members of the public who are still holding onto 1-cent coins can continue to utilise them.

First Series (1967 - 1985)

The First Series of circulation coins was issued on 20 November 1967. These coins, displaying various designs, represented a dramatic break from the past, as coins issued by previous currency commissions had borne only the effigy of the reigning British monarch on the obverse. This was a reflection of the new status which Singapore had gained as an independent republic in 1965.

The coins in this series have a common reverse design. The denomination of the coin is in the centre with the year-date at the top. Two stalks of paddy are on the left with the word "SINGAPORE" on the right.
