1 oz Silver Australian Koala Bullion Coin .999 Fine

The Silver Australian Koala is a 1 troy oz .999 fine silver sovereign coin struck by the renowned Perth Mint and backed by the Australian government with a $1 AUD face value. Collectors and silver stackers alike are drawn to this series because the reverse Koala design changes every single year, making each annual release a distinct piece rather than a repeating issue. With mintage capped at 300,000 coins per year for the 1 oz size, availability is limited, and the series has been running continuously since 2007.

Frequently Asked Questions

What exactly is the Silver Australian Koala 1 oz coin?

It is a 1 troy oz silver bullion coin produced by the Perth Mint in Australia. The obverse features a right-facing portrait of Queen Elizabeth II along with the coin's $1 AUD face value, while the reverse showcases a Koala design that is updated each year. As a sovereign coin, it carries the full backing of the Australian government.

What are the weight, purity, and dimensions of this coin?

The coin weighs 1 troy oz and is struck in .999 fine silver. It measures 40.6 mm in diameter and 2.98 mm in thickness. Note that certain years — for example, the 2021 release — were upgraded to .9999 fine silver purity.

Why does the design change every year, and does that affect value?

The Perth Mint intentionally issues a new Koala reverse design for every annual release in this series, which has been a defining feature since the series launched in 2007. Each year's coin is visually unique, which adds a collectibility dimension on top of the coin's base silver content. The annual mintage for the 1 oz size is capped at 300,000 coins, so no single year's design can be produced in unlimited quantities.

How is the coin packaged when I receive it?

Each Silver Australian Koala 1 oz coin ships in protective packaging to help preserve its condition. The Perth Mint's mark is associated with the coin, though it does not appear directly on the coin's face.

Is this coin eligible to be held in a precious metals IRA?

Silver coins held in an IRA must meet a minimum fineness of .999. The Silver Australian Koala 1 oz meets that standard at .999 fine silver (and exceeds it in years struck at .9999), making it eligible for inclusion in a self-directed precious metals IRA under IRS rules.

What if I order this coin — will I receive a specific year or a random date?

This coin is available either in specific listed years or as a random-year option. When the random-year version is ordered, the date is the Perth Mint's choice, meaning you will receive a genuine 1 oz Silver Australian Koala but the exact year cannot be assured in advance.
