How to Spot a Fake Koala
Counterfeit 1 oz Silver Australian Koala coins are increasingly common. Use the acoustic verifier above as your first line of defense, then check these key red flags:
- 🚨Incorrect weight (should be exactly 31.1g)
- 🚨Wrong diameter (should be 40.6mm) or thickness (should be 2.98mm)
- 🚨Flat or dull sound instead of sustained bell-like ring
- 🚨Magnetic attraction (genuine .9999 silver is not magnetic)
Tip: Sophisticated counterfeits can fool visual inspection alone. Always use the acoustic verifier above alongside precise weight and dimension measurements.
About the Koala
First issued in 2007 by the Perth Mint, the Silver Koala features one of Australia's most beloved animals with a new design each year. The coin rapidly became popular among collectors due to its annual design changes, .9999 silver purity, and the Perth Mint's reputation for exceptional strike quality.
