How to identify genuine coins

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.

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

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.
