How to Buy Physical Gold: Coins, Bars, Premiums, and Storage

Most online gold coverage stops at the spot price. The number on a live XAU/USD chart tells you what an ounce of gold is changing hands for between large institutions in the wholesale market — but it is not the price you will pay if you walk into a coin shop or order a kilobar from a refiner. The gap between those two prices, the choices that drive it, and what to do about it are the practical core of physical gold ownership.

This is a walkthrough of how a private buyer actually goes from "I want to own some gold" to "I have a coin or bar I can hold." It assumes no prior knowledge and does not push any specific dealer, mint, or product. For paper exposure to gold instead — funds, futures, mining equities — see our guide to gold ETFs and overview of gold mining stocks.

Why physical, when ETFs exist?

The honest answer is: for most portfolios, an ETF is a more efficient way to express a view on the gold price. Lower transaction costs, intra-day liquidity, no storage, no insurance, no premium-over-spot dragging on returns. Buyers who still choose physical typically do so for one of three reasons:

• Direct ownership of the metal. An ETF share is a claim on a fund that holds gold in a vault. A coin in your hand is the gold itself. For some buyers, that distinction is the whole point.
• Counterparty risk concern. Physical gold held outside the banking system has no third-party promise attached to it. That feature has value to a buyer who is specifically trying to diversify away from financial-system exposure.
• Privacy or transferability. A small coin collection can be moved, gifted, or stored privately in ways that a brokerage holding cannot.

None of these reasons is wrong, and none of them makes physical gold a "better" investment than the same dollar amount in an ETF. They are different products serving different needs. Decide which need you are meeting before you pick a format.

Coins versus bars: what each format is good for

Once you have decided to buy physical, the next decision is the form factor. The two main categories are sovereign coins and refiner bars.

Sovereign bullion coins

Government-issued coins — produced by national mints in standard weights, typically one troy ounce or fractions thereof. They are recognised globally, sold by virtually every dealer, and easy to resell. They are the closest thing physical gold has to a default product.

Trade-offs:

• Higher premium over spot. A one-ounce sovereign coin typically carries the largest dealer markup of any standard product, because production cost per ounce is highest at small denominations.
• Universal recognition. When you sell, the buyer almost certainly knows the coin and will offer something close to spot without requiring an assay.
• Smaller denominations cost more per ounce. A 1/10-ounce sovereign coin will carry a higher percentage premium than its one-ounce counterpart from the same mint. Useful if liquidity at small sizes matters; expensive if you are simply trying to accumulate ounces.

Refiner bars

Privately produced bars from accredited refiners. Available in a wide range of sizes, from one gram up through kilobars and 400-ounce London Good Delivery bars (the size used in wholesale markets and well outside the retail market).

Trade-offs:

• Lower premium over spot at common retail sizes (typically 1 oz, 10 oz, 100 g, 1 kg). The bigger the bar, the lower the percentage premium.
• Resale is dealer-dependent. A bar from a less well-known refiner may be discounted or require an assay before resale at full spot.
• Tamper-evident packaging matters. Modern bars usually ship in sealed assay cards that include a serial number and verification features. Once that seal is broken, resale value can fall.

What about numismatic and "premium" coins?

A separate market exists for collector coins where the value is tied to rarity, condition, or historical interest rather than the underlying metal. These are not a gold-price play. They are a collectibles play that happens to use gold as a substrate. If your goal is gold exposure, sovereign bullion or refiner bars will get you more ounces per dollar.

Premium over spot: the most important number you've never been told

The "premium" is the difference between what you pay your dealer and the wholesale spot price at the moment of the trade. It is quoted as a percentage. Premium has nothing to do with gold being expensive or cheap; it is the cost of converting a wholesale ounce into a retail product.

Premium is built from several layers:

1. Refining and minting cost — turning a London Good Delivery bar into a one-ounce coin or smaller bar.
2. Dealer margin — the dealer's gross profit on the trade.
3. Liquidity premium — extra margin charged on smaller, more in-demand denominations.
4. Tax and shipping — depending on your jurisdiction, sales tax or VAT may apply (investment-grade gold is exempt in many regions but not all).

Two practical implications:

• Ounce for ounce, larger products are cheaper. A kilobar will almost always have a lower percentage premium than the same dealer's one-ounce coins. That is why ratio-trading or accumulation buyers gravitate toward bars and away from fractional coins.
• Premiums move with retail demand, not the spot price. When retail buyers panic, premiums on small coins can blow out even while spot is flat. When demand is calm, premiums compress. A buyer waiting for "gold to come down" sometimes loses more to expanding premiums than they save on the lower spot price.

Always compare quotes on a "total all-in" basis: the dollar price for the product, including premium and any shipping or fees, divided by the metal weight. That gives you a per-ounce figure that is directly comparable to spot.

Where to buy

Physical gold is sold through three broad channels:

• Bullion dealers (online and bricks-and-mortar). The mainstream channel. Pricing is transparent, products are well-recognised, and most dealers publish live spot-linked pricing. Look for dealers that have been operating for more than a market cycle and that publish a clear buy-back policy.
• Government and refiner shops. Some national mints and large refiners sell directly to retail. Premiums are not necessarily lower than via dealers, but provenance is unambiguous.
• Private sales and auctions. Lower friction in some cases, but verification of authenticity sits entirely with the buyer. For a first purchase, this is generally not the channel to use.

Two warning signs that should end the conversation: pricing that does not move with the spot market, and aggressive cross-selling of "rare" or "graded" coins to a buyer who came in for bullion. Both are hallmarks of a sales operation rather than a bullion dealer.

Verifying what you bought

Counterfeiting is rare for sovereign bullion coins from major mints because the security features are difficult to replicate at the price points where forgery would be profitable. It is more common — though still uncommon — for unsealed bars from less well-known refiners. Three checks are worth doing on receipt:

• Weight and dimensions. Gold's density makes both very specific. A digital scale and a calliper will catch the great majority of bad fakes immediately.
• Sealed packaging on bars. Reject bars that arrive with broken or tampered assay cards. The serial number on the card should match the bar.
• Sound and appearance for coins. Sovereign coins have known design and edge features. A reputable dealer will be happy to walk you through them on a first purchase.

Specialist verification (XRF, ultrasonic thickness gauges) is a service some dealers offer and is worth using for larger bar purchases.

Storage

Physical gold is only as secure as where you keep it. The main options:

• At home. The most private option, and the one with the most personal risk. A high-quality safe, bolted to the structure, in a non-obvious location is the minimum bar. Insurance is rarely included by default in standard home cover and may need to be purchased separately, often with limits.
• Bank safe deposit box. Familiar, but availability has shrunk in many countries and the contents are typically not insured by the bank.
• Allocated vault storage. Specialist precious-metals vaults (often outside the banking system) hold specific, identified bars or coins under your name. You pay an annual storage fee, usually a fraction of a percent of value. Allocated storage is the closest thing physical gold has to "hands-off" ownership.
• Unallocated storage. The vault owes you a quantity of gold but does not hold specific bars assigned to you. This is closer to a deposit relationship than to direct ownership and reintroduces counterparty risk — one of the things many physical buyers were trying to avoid in the first place.

For larger holdings the practical default is allocated vault storage with a reputable provider. For smaller holdings, a quality home safe may be sensible. The dividing line is usually the point where an annual storage fee is cheaper than the marginal cost of upgraded home security and insurance.

Selling, when the time comes

Resale value depends almost entirely on three things: the recognisability of the product, the condition of the packaging or coin, and the current premium environment. Sovereign bullion coins from major mints are easiest to sell — most dealers will quote a buy-back close to spot on sight. Sealed bars from accredited refiners are next. Unsealed or unknown bars may require an assay and are typically discounted in the meantime.

Most buyers eventually realise that the round-trip cost of physical gold (premium on the way in plus discount on the way out, plus any taxes) makes it a better long-hold than a trading vehicle. If you want to actively trade the gold price, a fund or a futures position is almost always more efficient. The gold/silver ratio piece on this site discusses how those tools are used in practice.

Common mistakes

• Buying small coins because they "feel safer." A 1/10-ounce coin can carry double the percentage premium of a 1-ounce equivalent. For accumulation, that is a meaningful drag on returns.
• Confusing collectibles with bullion. A graded "premium" coin is a collectibles bet, not a gold-price bet.
• Not factoring in storage and insurance. A 0.5%/year storage cost is small in absolute terms but compounds against your total return.
• Selling into expanded premiums and buying back into normal ones. Round-trips work best when premium conditions are similar at both ends.
• Concentrating with a single dealer or vault. For substantial holdings, spreading across more than one provider is the simplest form of risk management.

A practical checklist before your first purchase

1. Decide why you are buying physical specifically, rather than a fund or mining equity.
2. Pick the format (sovereign coin or refiner bar) that matches your end goal — recognisability versus low premium per ounce.
3. Compare two or three reputable dealers on a total-all-in basis, not headline spot.
4. Verify on receipt: weight, dimensions, sealed packaging.
5. Decide where it will live — home safe, allocated vault, or a mix — before you place the order.
6. Document what you bought (product, weight, serial number, dealer, price, date) for tax and estate purposes.
