What Is Australia’s Silver Bullion Coin?
The Silver Australian Kangaroo is the Perth Mint’s flagship silver bullion coin, produced since 2016. It contains 1 troy ounce of .9999 fine silver, the highest purity among major silver bullion coins. The coin carries legal tender status in Australia with an AUD $1 face value and features a new kangaroo design on the reverse each year.
The .9999 purity (four nines) is a meaningful differentiator. Most competing silver coins are .999 fine: the American Silver Eagle, Silver Britannia, and Silver Philharmonic are all three-nines pure. Only the Canadian Silver Maple Leaf matches the Kangaroo’s .9999 standard. While the practical difference between .999 and .9999 is negligible for investment purposes (0.09% purity gap), four-nines purity carries a perception advantage for buyers who prioritize maximum refinement.
The Perth Mint, a wholly owned subsidiary of the Government of Western Australia, backs every Kangaroo with an explicit government guarantee for weight and purity under the Gold Corporation Act of 1987.
Design
Obverse: The Monarch
The obverse carries the reigning British monarch’s portrait. Coins through 2022 feature Queen Elizabeth II, and coins from 2023 onward feature King Charles III.
Reverse: Annual Kangaroo Designs
The reverse features a new kangaroo design each year, maintaining the tradition established by the Gold Kangaroo series. Designs depict kangaroos in various poses: hopping, standing, in outback landscapes. The annual change adds mild collector interest, though, as with the gold version, the year-to-year premium impact is minimal compared to coins like the Chinese Panda.
Prior to 2016, the Perth Mint produced silver coins under the “Kookaburra” and “Koala” series. The Kangaroo consolidated the silver bullion program under the same brand as the established gold series.
Specifications
| Attribute | Value |
|---|---|
| Silver Content | 1.0000 oz (31.1035g) |
| Gross Weight | 1.0000 oz (31.1035g) |
| Diameter | 40.60mm |
| Thickness | 4.00mm |
| Face Value | AUD $1 |
| Purity | .9999 fine silver |
| Edge | Reeded |
The 40.60mm diameter matches the American Silver Eagle and is larger than the Silver Britannia (38.61mm) and Silver Philharmonic (37.00mm). The 4.00mm thickness is notably chunkier than most competitors, giving the Kangaroo a substantial feel. For side-by-side comparisons with other bullion coins, see the coin specs lookup.
How Do Silver Kangaroo Premiums Compare?
The Silver Kangaroo positions competitively in the mid-range of sovereign silver coin premiums:
| Coin | Typical Premium Over Spot | Dollar Amount (at $30 silver) |
|---|---|---|
| Silver Philharmonic | 18-30% | $5.40-9.00 |
| Silver Kangaroo | 20-35% | $6.00-10.50 |
| Silver Maple Leaf | 20-35% | $6.00-10.50 |
| Silver Britannia | 25-40% | $7.50-12.00 |
| Silver Eagle | 30-50% | $9.00-15.00 |
The Kangaroo typically trades near Maple Leaf pricing, sometimes slightly above or below depending on dealer inventory and promotions. It is consistently cheaper than the Eagle and Britannia, and often slightly more than the Philharmonic.
Quantity pricing: Kangaroos are available in tubes (25 coins) and monster boxes (250 coins, 10 tubes of 25). Perth Mint monster boxes contain 250 coins rather than the 500-coin format used by most other mints. This means a Kangaroo monster box is roughly half the size and investment of an Eagle or Maple Leaf monster box, making it more accessible for smaller-scale buyers.

Is the Silver Kangaroo IRA Eligible?
Yes. The Silver Kangaroo’s .9999 purity exceeds the IRS minimum of .999 fine for silver in self-directed IRAs. It is accepted by all major precious metals IRA custodians.
The Kangaroo’s competitive premiums and four-nines purity make it a solid IRA option. For investors choosing between the Kangaroo and the Maple Leaf for an IRA (both .9999, similar premiums), the decision often comes down to whichever is cheaper at the specific dealer and purchase date.
Silver Kangaroo vs American Silver Eagle
| Factor | Silver Kangaroo | Silver Eagle |
|---|---|---|
| Purity | .9999 | .999 |
| Weight | 1 oz | 1 oz |
| Face Value | AUD $1 | $1 |
| Premium | 20-35% | 30-50% |
| Security Features | None standard | None |
| Design Changes | Annual | Fixed (Type 2) |
| US Liquidity | Moderate | Highest |
| IRA Eligible | Yes | Yes |
The Eagle’s premium advantage is its unmatched liquidity in the US market. Every coin shop in America buys Eagles without hesitation and at tight spreads. Kangaroos are less universally recognized domestically, though all major online dealers buy them readily.
The Kangaroo’s premium savings of $3-5 per coin add up quickly. For a 100-coin purchase, that is $300-500 in savings. For buyers who will sell through online dealers rather than local shops, the Kangaroo offers more silver per dollar without a meaningful liquidity penalty.
Silver Kangaroo vs Canadian Silver Maple Leaf
This is the most direct comparison, as both are .9999 fine:
- Purity: Identical at .9999.
- Premium: Very close, typically within $0.50-1.00 per coin. The Maple Leaf sometimes beats the Kangaroo, and vice versa, depending on dealer inventory and promotions.
- Security: The Maple Leaf has MintShield technology, micro-engraved maple leaf privy mark, and radial lines. The Kangaroo has no comparable features. Edge: Maple Leaf.
- Monster box size: Kangaroo boxes hold 250 coins; Maple Leaf boxes hold 500 coins. This makes the Kangaroo box more accessible ($7,500-10,000 vs $15,000-20,000) but less efficient per box on premiums.
- Global liquidity: The Maple Leaf has deeper worldwide distribution. The Kangaroo is stronger in Asia-Pacific markets.
- Design: The Kangaroo changes annually; the Maple Leaf is fixed. Mild collector advantage to the Kangaroo.
For most buyers, these coins are interchangeable. Buy whichever is cheaper at the time of purchase.
Perth Mint Government Guarantee
Every Silver Kangaroo carries the explicit guarantee of the Government of Western Australia under the Gold Corporation Act of 1987. This guarantee covers both weight and purity. While all sovereign mints implicitly guarantee their products, the Perth Mint’s statutory guarantee is one of the most formally structured in the industry.
This guarantee means the Perth Mint stands behind every coin it produces. Buyers who encounter a defective or underweight coin have recourse through the Mint and, ultimately, through the Western Australian government. In practice, quality control at the Perth Mint is excellent, and warranty claims are extremely rare.

Buying tip: The Silver Kangaroo’s 250-coin monster box is ideal for buyers who want bulk pricing but find 500-coin boxes too large an initial commitment. At roughly $7,500-10,000 per box (depending on silver prices and premiums), it is a lower entry point to monster box pricing than competitors’ 500-coin format.
Frequently Asked Questions
Is the Silver Kangaroo the same as the Silver Kookaburra?
No. The Kookaburra is a separate Perth Mint silver coin series that has been in production since 1990. The Silver Kangaroo launched in 2016 as a dedicated bullion coin, while the Kookaburra is positioned as both bullion and collectible. The Kangaroo is .9999 fine; the Kookaburra is .999 fine. For pure bullion investment, the Kangaroo is the better choice due to its higher purity and positioning as a focused bullion product.
Why is the Silver Kangaroo monster box only 250 coins?
The Perth Mint chose a 250-coin monster box format rather than the 500-coin standard used by the US Mint, Royal Canadian Mint, and Royal Mint. The smaller box size reduces the dollar commitment for bulk buyers and is easier to handle physically (approximately 17 pounds vs 34 pounds for a 500-coin box). Per-coin premiums in 250-coin boxes are still meaningfully lower than individual or tube pricing.
Does the annual design change affect the Kangaroo’s value?
Minimally. Unlike Chinese Pandas, Silver Kangaroo vintage years do not develop significant collector premiums. Year-to-year differences are typically $0.25-1.00 per coin, well within normal market spread. The annual design adds visual variety but does not meaningfully impact investment value.
How does Silver Kangaroo purity compare to other silver coins?
The Silver Kangaroo’s .9999 purity ties the Silver Maple Leaf as the purest major silver bullion coin. The Silver Eagle, Silver Britannia, and Silver Philharmonic are all .999 fine. The practical difference is 0.09%, or roughly $0.03 per ounce at $30 silver. The purity difference is more of a marketing distinction than a meaningful financial advantage.
Can I buy Silver Kangaroos in the US easily?
Yes. All major US online dealers carry Silver Kangaroos as standard inventory. Availability is consistent and rarely constrained. While less commonly stocked at local coin shops compared to Eagles, online purchasing makes Kangaroos as accessible as any other sovereign silver coin for US buyers.
