Identifying Genuine Currency

Our currency notes and coins have various advanced security features, including visually recognisable security features, machine-readable features and covert features. While the number of counterfeit Singapore currency is very low, the public is advised to be vigilant and to familiarise themselves with the key security features of genuine currency. 

Identifying Genuine Notes

The security features in Singapore's currency notes act as a safeguard to minimise the risk of counterfeiting. 

Look out for these security features in the paper and polymer notes.

Security Features of the Paper Notes

Incorporated in each currency note is a multiplicity of security features which makes the counterfeiting of currency notes extremely difficult. The best method of detection is to compare a suspect note with a genuine note. Security features of Portrait series notes are set out below.

Security Features of the Polymer Notes

Polymer notes are printed on a specialised polypropylene plastic that is derived from petroleum, and this material is not available commercially for security control purposes. The material starts as a clear plastic film, which is produced using unique patented production processes. The clear film is coated with multiple layers of materials, on which the features of the notes can then be printed. During the coating process an extensive range of security features are incorporated.

The $2, $5 and $10 polymer notes have security features unique to the polymer technology such as the Complex Clear Window.

Intaglio Portrait
Genuine Description
  The portrait of the late President Yusof bin Ishak dominates the front of the Portrait series notes. Hand-engraved and printed in intaglio ink, the portrait serves as a unique anti-counterfeiting feature. The fine lines of the engraving are difficult to imitate or reproduce.
Intaglio Prints
Genuine Description

The intaglio (raised) printing gives the note an embossed feel. Widespread use of this intaglio printing on the Singapore Arms, the engraved portrait, the word SINGAPORE and other areas offers good overall tactility. The prints are finely done so that tiny details are clearly defined. The intaglio printing of the denomination numeral of each note also helps recognition by the visually handicapped.
Each note has a Braille code printed in heavy intaglio ink at the top right corner of the front of the note, so that visually handicapped users can recognise the different denominations by touch.

This background shimmers in an array of colours when rotated. These features are unique properties to the kinegram and cannot be replicated.

Paper Notes
Invisible Fluorescent Fibres

When the note is viewed under UV light, more security features show up. Unlike most commercial papers, the paper of the note does not reflect UV light at all. Fibres which are invisible to the unaided eye are incorporated on both sides of the note surface. The fibres which cannot be seen in ordinary light will glow under UV light. This security feature can only be found on paper notes. 

Identifying Genuine Coins

Genuine coins typically have sharp and defined relief of the design, milled edges, lettering and characters on both sides of the coin. The weight of the genuine coin is also within the standard tolerance of the gazetted coin specifications.

For the Third Series $1 coin, visual security features include:

  • Laser mark micro-engraving. The orchid-shaped laser mark on a genuine coin will show a dense micro-pattern of circles under magnification.
  • Bi-metallic composition. Attempts to replicate bi-metallic coins are usually made using paint instead of two different types of metal.

Counterfeit Coins

Here are some general indicators that a coin may be a counterfeit:

  • Milling or edge patterns are uneven, poorly defined and worn off.
  • The relief of the design, lettering and characters are not distinct, sharp or well defined.
  • Surface of the coin has many pitmarks and appears very porous.
  • Diameter, thickness and weight of fake coins are different from the gazetted coin specifications.
  • The orientation of the obverse and reverse designs is not aligned.

When in possession of suspected counterfeit currency, one should:

  • Refrain from using the currency as circulating counterfeit currency is a criminal offence under the Penal Code.
  • Take down the particulars of the person or name of the retailer who dispensed the counterfeit currency.
  • Keep the currency in the condition as it was received. If it is a note, do not cut it or write anything on it.
  • Approach MAS to verify the authenticity of the currency.
  • If the currency is established as a counterfeit, lodge a report at any police station.
