Physical Gold 101: Coins, Bars, and What Actually Matters

Once someone decides to hold physical gold, the next question is usually about form — coins or bars — and it's a more practical decision than people expect. If you haven't settled on the metal yet, start with choosing between gold and silver first.

Coins vs bars: the real differences

Government-minted coins (American Gold Eagle, Canadian Gold Maple Leaf, and similar) carry a recognized, standardized purity and are widely accepted, which makes them easier to sell later. They typically carry a higher premium over the spot gold price than bars do, because of minting costs and that recognizability.

UK buyers work with a slightly different shortlist: Britannia and Sovereign coins from the Royal Mint are the recognised standard there, and because they are UK legal tender their tax treatment differs from generic bullion — HMRC sets out how capital gains and VAT apply to investment gold.

Bars, particularly from accredited refiners, usually carry a lower premium over spot price, meaning more of your money goes toward the actual metal rather than production and branding costs. The trade-off is that resale sometimes takes a bit more verification, since bars vary more by refiner and size.

For most people building a retirement-focused position, a mix of both is common: coins for liquidity and easy resale, bars for cost efficiency on larger allocations.

Purity and certification

Investment-grade gold is typically .999 or .9999 fine (99.9%-99.99% pure). Reputable coins and bars come with certification from recognized refiners or mints, and for IRA-eligible gold specifically, the IRS has minimum fineness requirements that must be met for the metal to qualify inside a self-directed IRA.

This is one area where cutting corners costs money later — uncertified or non-standard products are harder to resell at fair value and, in an IRA context, may not even be eligible.

Storage: home vs depository

For gold held outside a retirement account, home storage is legal and common, though it shifts insurance and security entirely onto the owner. For gold held inside a self-directed IRA, the IRS requires storage through an approved depository — home storage isn't permitted for IRA-held metals, regardless of what any company might imply.

Depository storage typically comes with an annual fee, but includes insurance and third-party verification, which matters both for security and for maintaining the IRA's tax-advantaged status.

What actually matters when buying

• Confirm purity and certification before anything else
• Understand the premium over spot price you're paying, and why
• If it's for an IRA, confirm IRS eligibility before purchasing — not after
• Factor in storage costs and method as part of the total cost, not as an afterthought

Certification and eligibility are also the clearest test of a seller: evaluating a dealer or IRA company largely comes down to whether they will put purity, premium, and depository details in writing before you buy.
