1.5 oz Platypus Silver Coin

A Distinctly Australian Silver Bullion Coin

The 1.5 oz Perth Mint Platypus is a .9999 fine silver coin that trades on one of the most recognisable animals in Australian fauna. The platypus is endemic to eastern Australia and Tasmania, and no other sovereign mint produces a platypus bullion coin, giving this piece a genuine monopoly on the subject matter. Perth Mint introduced the platinum version of this series in 2011 before releasing silver variants in 2021, with the 1.5 oz size joining a growing range of non-standard weights from the Perth Mint stable.

The 1.5 oz denomination puts this coin in a niche populated primarily by the Royal Canadian Mint's wildlife programme, where coins like the 1.5 oz Snow Falcon, 1.5 oz Polar Bear, and 1.5 oz RCM Wildlife have established the format. Perth Mint's entry brings .9999 purity (matching the RCM standard) and Australian legal tender status, with a $2 AUD face value. For stackers building positions in physical silver, the Platypus delivers 50% more metal per coin than a standard 1 oz silver coin with a proportionally lower per-ounce premium.

The coin features Natasha Muhl's design of a platypus swimming beneath lily pads in its natural freshwater habitat, capturing the animal mid-stroke with its distinctive duck-like bill and beaver-like tail visible. The design remained consistent from the platinum era, providing continuity across the programme. At 40.9 mm diameter and 5 mm thickness, the coin has a substantial feel that distinguishes it from thinner 1 oz pieces.

Perth Mint Platypus 1.5 oz Silver Specifications

The Perth Mint guarantees weight and purity on all bullion products. The coin carries the "P" mint mark identifying Perth as the production facility. Standard packaging includes individual capsules (32 mm) or tubes of 20 coins. The unlimited mintage distinguishes this from the platinum Platypus, which was capped at 30,000 per year during its 2011-2019 production run.

The .9999 purity places the silver Platypus at the highest standard in bullion coinage, matching the 1.5 oz Maple Leaf and exceeding the .999 standard used by many sovereign mints. This four-nines purity means the coin contains 46.655 grams of pure silver with negligible base metal content.

Tax Treatment for Silver Platypus Coins

As Australian legal tender struck in .9999 fine silver, the Platypus qualifies for investment-grade bullion tax treatment in several jurisdictions, though silver faces less favourable treatment than gold in most countries.

Australia

GST-free as investment-grade bullion. The coin meets all requirements: silver purity of 99.9% or above, produced by an accredited refiner, in a form commonly traded on commodity markets. Capital gains tax applies on disposal, with a 50% CGT discount available for assets held longer than 12 months.

United Kingdom

Silver coins carry 20% VAT on purchase regardless of legal tender status (only gold qualifies for the investment gold VAT exemption). The Platypus is not CGT-exempt since it is not UK legal tender. Margin scheme pricing may be available on pre-owned examples, reducing the effective VAT to the dealer's profit margin only.

United States

Sales tax treatment varies by state. The .9999 purity exceeds the .999 minimum for precious metals IRAs, making the coin IRA-eligible. Capital gains on silver bullion are taxed at the 28% collectibles rate for holdings over one year.

Canada

GST/HST exempt as investment bullion meeting the 99.9% purity threshold. The coin qualifies regardless of its Australian rather than Canadian origin.

Singapore

Qualifies as an Investment Precious Metal (IPM) under Singapore's GST exemption scheme, as it meets the 99.9% silver purity requirement and is legal tender from a recognised sovereign mint. No capital gains tax applies in Singapore.

Platypus vs Other 1.5 oz Silver Coins

The 1.5 oz silver coin market is dominated by Royal Canadian Mint releases, with Perth Mint offering fewer options at this weight. The Platypus competes primarily on design distinctiveness and Australian provenance rather than on price or availability.

Against the 1.5 oz RCM Snow Falcon, both coins share .9999 purity and similar dimensions (38-40.9 mm diameter). The Snow Falcon has a $8 CAD face value versus the Platypus's $2 AUD, though face values are symbolic in both cases. The Snow Falcon was a single-year 2016 release packaged in tubes of 15, compared to the Platypus's tubes of 20.

The 1.5 oz RCM Wildlife series offers a six-coin collection theme (2011-2013) depicting North American animals, with 1,000,000 mintage per design. The Platypus is unlimited in mintage but likely produced in smaller quantities due to narrower market demand. Both carry the same .9999 purity standard.

Compared to the 1.5 oz Polar Bear, the Platypus offers a uniquely Australian subject that no competitor can replicate. The Polar Bear benefits from broader recognition in the RCM 1.5 oz programme and stronger secondary market presence due to higher production volumes and longer market history (the Polar Bear launched the RCM 1.5 oz programme in 2013).

For buyers choosing between a Perth Mint 1.5 oz coin and the RCM alternatives, the decision often comes down to regional preference and dealer availability. Australian buyers will find the Platypus more readily available domestically, with the added benefit of direct Perth Mint support and guarantee. North American buyers have easier access to RCM coins through their established dealer networks.
