Perth Mint products have long had a reputation for exceptional quality, and the Australian Kangaroo and Kookaburra series are among the most respected bullion coins worldwide. That reputation makes them attractive counterfeiting targets. Over the past five years, the volume of fake Perth Mint coins has increased substantially, driven largely by the same Chinese counterfeiting networks that produce fake American Eagles and Canadian Maple Leafs.
Perth Mint hasn't been passive about this. Their security features, particularly the micro-engraved letter introduced in 2016, give buyers a powerful authentication tool — if they know to look for it.
The Micro-Engraved Security Letter
Starting in 2016, Perth Mint introduced a micro-engraved letter on the reverse of their Kangaroo and Kookaburra coins. The letter is tiny — you need a 10x loupe or better to see it clearly — and it's placed within the design in a location that changes periodically. The letter itself is consistent for a given coin type and year.
The engraving is laser-cut at a precision that conventional die-making can't replicate. Under magnification, the genuine letter is sharp, clean, and perfectly formed with consistent line width. On counterfeit coins that attempt to include the letter (many don't even bother), it looks rough and imprecise — the lines are uneven, the letter shape is approximate rather than exact, and the scale is often slightly wrong.
If you're examining a Kangaroo or Kookaburra dated 2016 or later and cannot find the micro-engraved letter under magnification, the coin is almost certainly counterfeit. This is your fastest, most definitive check for modern Perth Mint products.

Perth Mint's Verification Service
For Perth Mint gold bars (and some coin products), every item carries a unique serial number that can be cross-referenced through Perth Mint's online verification service. You enter the serial number on their website and the system confirms whether that number corresponds to a genuine product, along with details about the product's specifications.
Counterfeiters have responded in two ways. Some fakes carry serial numbers that simply don't exist in Perth Mint's database — easy to check, easy to catch. More sophisticated operations use serial numbers copied from genuine products, so the number verifies as real, but multiple fakes share the same number. If you're buying from a secondary market seller, ask for the serial number before purchase and verify it. Then compare the physical product against the specifications the database returns. If the seller won't provide the serial number in advance, walk away.
The Kangaroo Design: What to Look For
Like Chinese Pandas, Perth Mint Kangaroos feature a reverse design that changes annually, showing the kangaroo in different poses and environments. This annual change makes authentication by design memory harder, but certain quality markers remain consistent.
On genuine coins, the kangaroo's fur shows fine texture with individually defined strands, particularly around the chest and shoulders. The ears have visible inner detail. The powerful hind legs show muscular definition with visible tendon lines. The tail has a tapered, organic form with surface texture.
Counterfeit kangaroos are smooth where they should be textured. The fur looks like skin, the ears are simple leaf shapes without interior structure, and the legs lack anatomical accuracy. The background terrain or vegetation (which varies by year) typically lacks the fine detail present on genuine coins — grass blades become vague lines, rocks become smooth lumps.
The Kookaburra: Feather Detail Is Everything
For the Silver Kookaburra series, feather detail is your primary visual authentication tool. The kookaburra bird on genuine coins shows remarkable feather definition. Each feather has a central shaft (rachis) with branching barbs. The overlapping layers of feathers on the wings and breast create a natural, three-dimensional appearance. The bird's head crest feathers are individually defined.
Fake Kookaburras render the bird as a shape with surface lines. The feathers are indicated rather than detailed — shallow grooves suggest feather boundaries without any of the internal structure that genuine coins display. The crest looks like a smooth bump rather than a spray of distinct feathers. Under magnification, the difference is dramatic.
The Lustre Problem
Perth Mint coins have a characteristic lustre that's difficult to fake. Genuine silver Kangaroos and Kookaburras have a bright, white lustre with a satiny quality to the fields (flat areas) and a more brilliant finish on the raised design elements. This contrast between field and design lustre is a result of the minting process and isn't easily replicated.
Counterfeit coins typically have a uniform lustre — either everything is equally shiny (common on electroplated fakes) or everything has the same matte finish (common on cast fakes). Some fakes have a distinctly greyish tone rather than the clean white of genuine .9999 silver. Others are suspiciously mirror-like, with a chrome-quality shine that silver doesn't naturally produce.
The Monarch's Portrait
All Perth Mint coins carry the portrait of the reigning British monarch on the obverse (Australia being a Commonwealth nation). The same portrait quality checks that apply to other Commonwealth coins work here: look for fine hair detail, precise lettering, and sharp definition on the crown and jewellery. Ian Rank-Broadley's fourth portrait of Elizabeth II (used 1998-2018) and Jody Clark's fifth portrait (2019-2022) are both finely detailed on genuine coins and soft or simplified on counterfeits.
For King Charles III portraits (2023+), the same principle applies — fine detail on genuine, soft detail on fake. The transition between monarchs also created a brief window of confusion that counterfeiters exploited, producing coins with mismatched dates and portraits.
Buying Perth Mint Products Safely
Perth Mint maintains a network of authorised distributors worldwide. Buying through these channels guarantees authenticity and typically includes sealed packaging that provides an additional layer of assurance. If you're buying on the secondary market, insist on seeing the micro-engraving under magnification for 2016+ coins, verify any serial numbers through Perth Mint's website, and don't accept prices that are significantly below current dealer pricing.
The Australian Kangaroo and Kookaburra series deserve their excellent reputation. Just make sure the coins you're buying are actually made by Perth Mint, not by a workshop in Shenzhen.
