Key Takeaways
- Silver bars or coins? If your goal is the most silver for your money, a 1 kg bar usually wins: on 21 October 2026 the cheapest 1 kg bar we tracked cost 7.9% over spot, against 11.4% for the cheapest 1 oz coin.
- Coins win on flexibility: you can sell one ounce at a time, and government-minted coins carry security features and a face value.
- Most 1 oz silver coins at Australian dealers cost 15% to 18% over spot, and imported coins such as the American Silver Eagle cost 24% to 35%.
- Postage hits small orders hard: a single 1 oz coin delivered cost 40% to 49% over spot in our data, while a delivered 1 kg bar stayed between 9.1% and 12.6%.
- Investment silver of at least 99.9% fineness is treated as precious metal by the ATO, so neither bars nor coins should carry GST.
Most new silver buyers face the same choice early on: silver bars or coins? Both hold the same metal. Yet the price you pay per ounce, the cost of selling and the ease of storing them can be quite different.
In this guide, we compare silver bars and coins using real listings from Australian dealers in our investment silver price comparison. You will see what each costs over spot, how postage changes the maths, what the ATO says about GST and which option suits your budget and plans.
Silver Bars vs Coins: The Short Answer
Here is a common rule of thumb: buy bars for weight, buy coins for flexibility. A large bar spreads the cost of making it over many ounces, so its premium per ounce is lower. A coin costs more per ounce, but it is easier to sell in small amounts and easier to recognise.
Does that mean bars are always better? No. On a budget under about A$2,900, a single 1 kg bar is out of reach, and small bars of 10 oz can cost as much over spot as coins. The right answer depends on how much you plan to spend and how you expect to sell.
- Bars: lowest premium per ounce, simple to stack, best for larger amounts.
- Coins: higher premium, legal tender, security features, easier to sell one at a time.
- Mix: many investors hold a core of 1 kg bars and a smaller layer of 1 oz coins.
What Is the Difference Between a Silver Bar and a Silver Coin?
A silver bar is a block of refined silver stamped with its weight, fineness and maker. A silver bullion coin is a piece of refined silver struck by a mint, usually a government mint, with a face value and a design. Both are bullion: products valued mainly for their metal content, not for rarity. Our bullion glossary entry explains the term in more detail.
Cast bars and minted bars
Most kilo silver bars sold in Australia are cast bars. Molten silver is poured into a mould, which leaves a slightly rough, rounded finish. Minted bars are cut from rolled silver sheet and pressed, so they look sharper and often come sealed in plastic. Cast bars usually cost less to make, which keeps their premium low.
Legal tender coins
Bullion coins carry a face value. The Perth Mint’s 1 oz Silver Kangaroo, for example, is A$1 legal tender. That face value is symbolic, since the silver is worth far more, but it ties the coin to a government issuer. The Perth Mint is owned by the Government of Western Australia.
What about silver rounds?
A silver round looks like a coin but is made by a private mint and has no face value. Rounds are pure silver bullion like coins, yet they usually sell for a lower premium because they carry no government guarantee. They are less common at Australian dealers than bars and legal tender coins.
Fineness
Fineness is the share of pure silver in the product. Most investment silver bars and coins sold in Australia are 99.9% or 99.99% silver. The Perth Mint’s Kangaroo coins are 99.99%, while the Silver Britannia and Silver Krugerrand are 99.9%. See our entry on fineness for how purity is marked.
Premiums: What Silver Bars and Coins Cost Over Spot
The premium over spot is the extra you pay above the value of the silver itself. It covers refining, minting, distribution and the dealer’s margin. On silver, it matters far more than on gold, because silver is cheap per ounce while the cost of making a coin is not.
How do you calculate it? Use this formula:
Premium % = (dealer price − spot value of the silver) ÷ spot value × 100
On 21 October 2026, the Metals Radar daily spot price for silver was A$82.15 per troy ounce. A 1 kg bar holds 32.15 troy ounces, so its silver was worth A$2,641.18. Here is what Australian dealers asked that day:
| Product | Dealer | Price (A$) | Price per oz (A$) | Premium over spot |
|---|---|---|---|---|
| 1 kg silver bar (various brands) | Ainslie Bullion | 2,848.77 | 88.61 | 7.9% |
| 1 kg GBA silver bar | Gold Stackers | 2,872.25 | 89.34 | 8.7% |
| 500 g GBA silver bar | Gold Stackers | 1,457.30 | 90.65 | 10.4% |
| 1 kg Perth Mint cast bar | The Perth Mint | 2,925.34 | 90.99 | 10.8% |
| 1 kg ABC cast bar | Australian Bullion Company | 2,944.00 | 91.57 | 11.5% |
| 10 oz ABC cast bar | Australian Bullion Company | 949.10 | 94.91 | 15.5% |
| 1 oz Kangaroo (various years) | Ainslie Bullion | 91.55 | 91.55 | 11.4% |
| 1 oz Maple Leaf | Australian Bullion Company | 94.55 | 94.55 | 15.1% |
| 1 oz Maple Leaf | Gold Stackers | 94.65 | 94.65 | 15.2% |
| 1 oz Britannia | Ainslie Bullion | 95.40 | 95.40 | 16.1% |
| 1 oz Kangaroo 2026 | The Perth Mint | 96.59 | 96.59 | 17.6% |
| 1 oz Philharmonic | Ainslie Bullion | 97.10 | 97.10 | 18.2% |
| 1 oz American Silver Eagle | Ainslie Bullion | 101.90 | 101.90 | 24.0% |
| 1 oz American Silver Eagle | KJC Bullion | 110.74 | 110.74 | 34.8% |
1 kg silver bars
Kilo bars were the cheapest way to own silver in our data. The four we tracked sat between 7.9% and 11.5% over spot. The gap between the cheapest and the dearest kilo bar was A$95.23, which is a good reason to compare dealers before you buy. You can track live offers, including those from Ainslie Bullion and The Perth Mint, on our 1 kg silver bar price comparison.
1 oz silver coins
Most 1 oz coins landed between 15.1% and 18.2%. The exception was Ainslie’s Kangaroo in various years at 11.4%, cheaper than two of the kilo bars. Older-year coins are often sold at a discount to the current year’s design. Imported American Silver Eagles were the most expensive coins we tracked.
Smaller bars: 500 g and 10 oz
Smaller bars do not always save money. The 500 g GBA bar cost 10.4% over spot, close to a kilo bar. The 10 oz cast bars at Australian Bullion Company cost 15.5%, about the same as a Maple Leaf. If you are paying coin-level premiums anyway, a coin gives you more flexibility for the same price.
So what does this mean in dollars? Buying 32.15 oz as 1 oz Britannias at A$95.40 each, instead of one 1 kg bar at Ainslie, would cost about A$218 more before postage. That is roughly 7.7% more for the same amount of silver. Read also: Gold Premium Over Spot in Australia: What You Really Pay.
Postage Changes the Maths on Small Orders
Premium tables usually leave out postage. That is fine for large orders, but on a single coin it can double the cost over spot. Our price service also records the postage each dealer quotes for an order of one item:
| Product and dealer | Price (A$) | Postage (A$) | Delivered (A$) | Delivered premium |
|---|---|---|---|---|
| 1 kg bar, Ainslie Bullion | 2,848.77 | 32.09 | 2,880.86 | 9.1% |
| 1 kg GBA bar, Gold Stackers | 2,872.25 | 47.98 | 2,920.23 | 10.6% |
| 1 kg cast bar, The Perth Mint | 2,925.34 | 49.68 | 2,975.02 | 12.6% |
| 500 g GBA bar, Gold Stackers | 1,457.30 | 36.66 | 1,493.96 | 13.1% |
| 1 oz Kangaroo 2026, The Perth Mint | 96.59 | 18.56 | 115.15 | 40.2% |
| 1 oz Maple Leaf, Gold Stackers | 94.65 | 25.76 | 120.41 | 46.6% |
| 1 oz Kangaroo, Ainslie Bullion | 91.55 | 31.00 | 122.55 | 49.2% |
The lesson is simple. If you buy coins, buy several at once or collect them in store. A single coin posted to your door can cost you almost half its silver value in extras.
GST on Silver Bars and Coins in Australia
Is there GST on silver in Australia? Not on investment silver. Under the ATO’s ruling GSTR 2003/10, silver of at least 99.9% fineness, in an investment form such as a bar or a bullion coin, counts as precious metal. The first sale by the refiner is GST-free, and later sales between dealers and investors are input taxed, so no GST is added to the price you pay.
This rule treats bars and coins the same way, so GST should not decide your choice. Watch out for two exceptions:
- sterling silver (92.5%) and older coins below 99.9% fineness do not qualify,
- jewellery and silverware are not investment forms, even when the silver is fine.
Selling at a profit is a separate question. Capital gains rules are set by the ATO, and your result depends on your situation, so check with a tax adviser before a large sale.
How Volatile Is Silver in AUD?
Before choosing a format, it helps to remember how much silver moves. Over the last 12 months, the AUD price climbed from A$77.20 on 21 October 2025 to a peak of A$165.70 on 29 January 2026. By 21 October 2026, it was back at A$82.15.
Why does this matter for bars vs coins? Because premiums are a fixed cost you pay upfront. A 16% premium on a coin needs a 16% rise in spot (plus the dealer’s buyback spread) just to break even. With swings this large, the extra few per cent on coins can look small, or very large, depending on when you sell. See the full history on our silver price chart.
Liquidity and Resale: Which Is Easier to Sell?
Liquidity is how easily you can turn silver back into cash at a fair price. Both formats sell well in Australia when they come from known makers. The difference is in the size of each sale.
Selling coins
Coins let you sell exactly what you need. Need A$300? Sell three or four coins and keep the rest. Coins from the Perth Mint, the Royal Canadian Mint and the Royal Mint are recognised by dealers across the country.
Selling bars
A 1 kg bar is a single unit worth more than A$2,600 at today’s spot. You cannot sell half of it. Bars from well-known makers such as The Perth Mint and ABC Bullion are easy to sell, while unknown brands may be tested before a dealer pays you, which can take time.
Dealers buy back at a price below their selling price. This gap is called the bid-ask spread, and it is often wider on products with higher premiums. Compare dealer buyback prices before you sell.
Storage: Bars Stack, Coins Need More Care
Silver takes up a lot of space for its value. On 21 October 2026, a kilogram of silver was worth about A$2,641, while one ounce of gold cost A$5,888.52. The same money buys a heavy bar of silver or a small coin of gold. How you store silver depends on the format:
- Bars: compact rectangles that stack neatly in a safe, with little risk of damage to resale value.
- Coins: best kept in tubes or capsules, since scratches and spots can lower what collectors and some dealers will pay.
Silver also tarnishes over time. On bars this rarely matters. On coins, toning or white “milk spots” can put off some buyers, even though the silver content is unchanged. Our guide on how to store precious metals safely covers home safes, bank boxes and vaults.
Counterfeits: Which Is Easier to Check?
Fake silver exists in both formats. Coins from government mints have one advantage: modern security features. The Silver Kangaroo carries a micro-engraved mark visible under magnification. Since 2014, the Silver Maple Leaf has radial lines and a micro-engraved leaf showing the year. Since 2021, the Silver Britannia has four security features.
Bars rely on the refiner’s stamp, weight, dimensions and, on many products, a serial number. A fake bar with the right weight and size is hard to make, but not impossible. Whatever you buy, buy from a known dealer. Learn the checks in our guide on how to spot a fake Silver Kangaroo.
Who Should Buy Silver Bars?
Bars make sense when cost per ounce matters most and you do not plan to sell in small pieces. Choose bars if:
- you plan to spend A$3,000 or more at a time,
- you want the lowest premium over spot,
- you plan to hold for years and sell in one go,
- you have a safe or vault with limited space.
Compare silver bar prices from Australian dealers, including 500 g silver bars for a smaller budget.
Who Should Buy Silver Coins?
Coins make sense when flexibility and recognition matter more than the last few per cent of premium. Choose coins if:
- you buy small amounts regularly, for example monthly,
- you want to sell part of your holding without breaking a bar,
- you value security features and a government issuer,
- you like the Perth Mint’s yearly designs.

A Mixed Approach Many Investors Use
You do not have to pick one side. A common approach is to buy most of your silver as 1 kg bars and keep a smaller part in 1 oz coins. The bars keep your average cost low. The coins give you change: small units you can sell without touching the core.
What about gold? If you are still deciding between metals, our comparison of gold vs silver investments looks at volatility, storage and premiums side by side, and the gold silver ratio chart shows how the two metals move against each other.
