Gold bullion bars: a practical guide to buying and storage

A London Good Delivery bar is 350 to 430 fine troy ounces of 995.0-fine gold — roughly 10.9 to 13.4 kilograms of refined metal, produced by an LBMA-approved refinery and traded between approved counterparties.

Gold bullion bars: a practical guide to buying and storage

The spot price that flashes across a screen is settled on that wholesale unit. The one-ounce bar a retail buyer clicks "buy" on in Ohio, Florida, or California has nothing to do with the wholesale chain. It is a separate product, with a separate cost stack, sold through a separate set of intermediaries, and the headline spot figure is the wrong number to anchor on. Anyone who treats spot as their entry cost has not yet read their own invoice.

The spot price is a wholesale yardstick, and retail sits at the other end of the chain

The arithmetic is not subtle. The U.S. Mint's pricing for American Eagle Gold bullion — issued in 1, 1/2, 1/4, and 1/10 ounce sizes — is built from the prevailing precious-metals market price plus a premium covering minting, distribution, and marketing. That premium pays for the blank, the strike, the assay, the assay card, the shipping tube, and the Authorized Purchaser's margin. The Mint explicitly tells buyers to understand both the spot and the premium before transacting. The LBMA makes the same point from the other side of the trade: a 1-gram bar is considerably more expensive on a like-for-like basis than a one-troy-ounce bar, because fixed fabrication costs are spread over less metal. The pattern holds across the entire retail shelf.

Spot is what 12.5 kilograms costs in a London vault. The retail bill is built on top of that number, not from it.

As the bar shrinks, the per-ounce premium grows. There is no scale economy in a 1-gram bar.

The "Good Delivery" stamp is not a retail label

LBMA Good Delivery is a specific wholesale specification: a bar of 350 to 430 fine troy ounces, minimum fineness 995.0 parts per thousand, produced by an approved refiner, weighed and assayed under Good Delivery rules. A typical Good Delivery bar is about 400 troy ounces, or roughly 12.5 kilograms. A one-ounce retail bar cannot meet that spec. It is not a Good Delivery bar in any sense the LBMA recognizes. It is a different product, made by a refiner, packaged for the retail channel, and sold through a separate retail chain with a separate cost stack. Major Swiss fabricators — PAMP, Argor-Heraeus, Valcambi, Metalor — typically ship retail bars with serialized packaging and a matching assay certificate, and that documentation has become the de facto standard at the high end of the market. Smaller cast bars from less prominent refineries, or fractional sizes sold at aggressive price points, do not always carry the same paper trail. Where a serial number is present, it is chain-of-custody proof, not a ticket into the wholesale vaulting system. Most retail bars are sold back to the same dealer or a competitor, often at a buyback spread wider than what a wholesale bar would clear between approved counterparties.

Cast vs. minted: two retail products, two cost stacks

A cast bar is poured into a mold, cooled, and stamped. Rougher finish, lower production cost, thinner premium over spot. A minted bar is blanked from a flat strip of refined gold, polished, and struck under high pressure; production scrap returns to the melt. That extra processing shows up in the premium. For an investor who is going to seal the bar in an assay card and never touch it, the practical question is what the dealer will pay to buy it back. That number depends on weight, fineness, and refiner reputation, not on whether the bar was cast or struck. The same logic applies to the choice between sovereign coins and private-mint bars: an American Eagle trades at a tighter spread in the U.S. retail market because the buyer pool is large and the authenticity question is settled by the U.S. Mint, while a private-mint bar from an LBMA-accredited refiner will still move but typically at a wider bid-ask gap.

Allocated vs. unallocated: this is the storage question that matters

When a U.S. retail buyer stores metal with a dealer or vault, the legal structure matters more than the location. Two products, often sold under similar names, are not the same thing.

An allocated account is backed by specific identified bars. The custodian should provide a bar list showing the unique bar number, gross weight, assay or fineness, and fine weight in ounces or grams. The customer owns those bars, even if they sit in a shared vault in Zurich, New York, or Salt Lake City. The LBMA notes that allocated accounts generally incur storage fees, billed by weight and time. The customer's position is a property interest, not a balance-sheet claim.

An unallocated account is a contractual claim against the account provider. The provider owes the customer metal of a certain weight and fineness; the provider does not earmark specific bars. If the provider fails, the customer is a general unsecured creditor — on the same footing as any other trade creditor — for the metal's value. Unallocated accounts generally incur maintenance fees instead of storage fees, and the amount and method vary by operator.

A practical detail that surprises first-time buyers: the ounces on an allocated statement will not be a round number. The LBMA's own worked example shows an intended 10,000-ounce purchase allocated as 9,993.213 or 10,012.345 fine ounces, because the account is built from the actual fine weight of the specific bars assigned. A statement showing exactly 10,000.000 is usually a marketing artifact, not an allocated position.

Allocated means you own specific bars. Unallocated means you own a promise.

The cost difference is real but not always intuitive. A low maintenance fee on an unallocated position is not necessarily cheaper than a higher storage fee on an allocated position once counterparty risk is priced in and the fact that, in a failure, unallocated customers are paid in cash, not metal.

The dealer is not federally regulated — and that is the whole story

The CFTC is explicit: retail precious-metals dealers are not federally regulated in the United States. There is no single federal licensing regime the way brokers, futures commission merchants, or banks are subject to. State regulators handle licensing in many states; the federal floor is low. That is not a comment on the industry; it is a description of how the regulatory map is drawn.

The CFTC's due-diligence guidance for retail buyers is direct. Check the dealer's physical address. Check how long it has been operating. Check its complaint history with consumer organizations and the relevant state authorities. Verify the registration status of the firm and its principals. State attorneys general and the FTC maintain public complaint records; the Better Business Bureau tracks dispute patterns across the industry, and a multi-year trail of unresolved complaints is a louder signal than a glossy website. None of this is a guarantee; skipping it leaves the buyer absorbing the full loss if the dealer is fraudulent or insolvent.

The fraud patterns are worth naming. The FTC's July 2025 alert flags a specific scam: a buyer is asked to purchase gold bars and hand them over to a courier, a "financial advisor," or another third party. Legitimate dealers and custodians do not ask retail customers to physically deliver bars to a private individual as part of an investment transaction. Any version of that request is a red flag and should be reported. The CFTC separately warns that fraudulent dealers have charged storage and insurance fees for metal that did not exist.

Insurance and storage fees on a statement are not proof the metal exists. They are line items on an invoice.

For physical storage, the realistic options are a bank safe-deposit box, a private vault operator, a dealer-arranged vault, or home storage. Each carries a cost stack and a risk stack. Bank safe-deposit boxes are inexpensive but offer limited insurance and restricted access hours, and FDIC coverage does not apply to their contents; they are not generally suited for IRA-held metal. Private vaults charge a recurring storage fee and typically carry their own insurance, often arranged through Lloyd's of London syndicates that specialize in specie coverage. Dealer-arranged vaults tie the buyer's storage to the same counterparty that sold the bar, simplifying buyback but concentrating counterparty exposure. Home storage removes the recurring fee and adds control, but removes the third-party custody that a future buyer, lender, or executor will look for. There is no universally cheapest or universally safest answer; the right choice depends on the size of the position and the buyer's tolerance for counterparty exposure.

The tax treatment is not what most buyers assume

For U.S. federal income tax, the IRS identifies gold, silver, and platinum bullion as collectibles. Long-term gains on collectibles are taxed at a higher maximum rate than ordinary long-term capital gains — 28% versus 15% or 20%, depending on bracket. Short-term gains are taxed at ordinary income rates. The IRS also confirms that gains on bullion held for investment are taxable capital gains, and that investment losses may be deductible as capital losses, subject to the standard rules. None of this is unique to physical metal; it is just the bracket the metal falls into.

The IRA exception is narrower than the marketing suggests. The IRS allows physical gold, silver, platinum, and palladium bullion inside a self-directed IRA, but only if the metal meets the relevant fineness requirement and is held in the physical possession of a bank or an IRS-approved non-bank trustee. Gold bars must meet a 99.5% fineness minimum to qualify; American Eagle coins are explicitly permitted regardless of fineness because the statute names them. The metal cannot sit in the account holder's home safe. If the IRA acquires an ineligible collectible, the account is treated as having distributed the cost of the acquisition in the year of purchase, and that deemed distribution is taxable. The custodian's job is to verify fineness and arrange storage at an approved depository; the buyer's job is to understand that the bar is no longer physically accessible without a taxable event.

State tax treatment varies and is not addressed by federal guidance. A handful of states collect sales tax on bullion purchases, others exempt investment-grade metal, and the threshold for "investment grade" is set at the state level. Buyers in states with a sales tax should confirm the exemption in writing before relying on it.

What this means for the spot price on the screen

The wholesale spot price is set on roughly 400-troy-ounce bars in London vaults, between approved counterparties, in a market that moves on tonnage, freight, refining capacity, and central-bank flows. A retail buyer in the U.S. is operating at the tail of that chain. The bar in the safe is the same element — the same 79 on the periodic table — but the price paid, the storage cost, the tax bracket, and the exit liquidity are all separate from the spot figure on the screen.

For anyone building a position in physical metal, the practical work is in the supply chain, not the ticker. Compare premiums on comparable bars from comparable refiners. Decide between allocated and unallocated before the first ounce is bought, because the decision is hard to reverse. Verify the dealer's physical address, history, and complaint record with the state regulator. For IRA-held metal, treat the IRS fineness rule and the approved-trustee custody rule as non-negotiable; a bar in a home safe is not an IRA asset, regardless of what the dealer says. The spot price will move on its own. The buyer's job is to make sure the cost stack, the storage structure, and the tax bracket are correct when it does.

FAQ

What is the difference between a cast bar and a minted bar?
A cast bar is poured into a mold with a rougher finish and lower production costs, while a minted bar is stamped from a flat strip of gold with a polished finish, resulting in a higher premium.
How can I tell if my gold storage is truly allocated?
An allocated account provides a bar list detailing unique serial numbers, gross weights, and assay information for specific bars, whereas a statement showing a perfectly round number of ounces is typically a marketing artifact.
Can I keep gold for my IRA in a home safe?
No, IRS rules require that physical gold held in a self-directed IRA must be stored in the possession of a bank or an IRS-approved non-bank trustee.
Why is the premium higher on smaller gold bars?
Fixed fabrication costs, such as minting and assaying, are spread over a smaller amount of metal, causing the per-ounce premium to increase as the bar size decreases.
What are the risks of an unallocated gold account?
In an unallocated account, you do not own specific bars but rather hold a contractual claim; if the provider fails, you become a general unsecured creditor for the value of the metal.
