The debate between gold bars and coins matters because the choice changes your costs, resale path and storage needs. For a safety-first saver or someone building a long-term allocation, the trade-offs are numeric: purity (24k versus 22k) determines fine weight, premiums and spreads determine your entry/exit cost, and storage/insurance determines ongoing expenses. This piece gives a pragmatic, data-first roadmap for buyers in the US, UK and EU. Expect concrete examples, a simple formula to calculate price per gram of fine gold, and decision rules tied to four drivers: purity, premiums, liquidity and storage. Read on for clear rules: coins for emergency liquidity and divisibility; bars for the lowest cost per gram when stacking long-term. Links to dealers, assay standards and additional reading are embedded for immediate follow-up.
60-Second Summary: Physical Gold Bars vs Coins — Quick decision guide
This section gives a compact, actionable summary for buying physical gold. It is written around the four drivers most retail investors should care about: purity, premium per gram, liquidity and storage cost. Use the bullets to match product to objective, then read the detailed sections for examples and numbers.
Three headlines you can act on now
- Coins = best for liquidity, small sales and gifting. Choose 1/10 oz → 1 oz denominations for quick walk-in resale.
- Bars = best cost per gram for long-term stacking. Aim for 50–100 g or 250 g–1 kg in vaults to minimize premium.
- When to pick each: if your priority is emergency cash, pick coins; for lowest cost per gram and compact long-term storage, pick bars.
Quick numeric example: a 1 oz coin with a premium of $30 over spot and a 100 g bar with a premium of $15 over spot — the bar will usually be cheaper per gram of fine gold. However, that coin is easier to sell in small amounts and often finds walk-in demand at local dealers or pawn shops.
Practical checklist before buying:
- Check the product purity (24k = .999–.9999; 22k = .9167) and compute fine weight.
- Calculate cost per gram of fine gold using the formula below.
- Confirm the dealer’s buy-back policy and visible spreads.
- Decide on storage: home safe, bank box, or allocated vault.
Cost per gram of fine gold: (Total price paid) ÷ (grams × purity). Example: $1,950 for a 1 oz coin (31.1035 g, .999 fine) → $1,950 ÷ (31.1035 × .999) ≈ $62.72 per gram of fine gold. Use this to compare coin versus bar offers precisely.

Purity & Formats: 24k versus 22k, coin denominations and bar sizes
Understanding purity and formats is fundamental. Purity determines how much fine gold you actually own; format affects premiums, recognizability and storage. This section details the most common purities and formats you’ll see on the market, using examples from major refiners and mints to clarify what to buy for different goals.
Purity explained: 24k (.999/.9999) vs 22k (.9167)
24k gold is sold as .999 or .9999 fine and is close to pure gold. Popular bars from LBMA-recognized refiners such as PAMP Suisse, Valcambi and Credit Suisse frequently advertise .9999 fine. Many sovereign coins — for example the Austrian Philharmonic (from the Austrian Mint) and the Canadian Maple Leaf (from the Royal Canadian Mint) — are issued at .9999 fine.
22k gold (.9167 fine) is a traditional standard for coins such as the South African Krugerrand (minted by Rand Refinery) and some British sovereigns. The lower fineness means part of the weight is alloy — this does NOT reduce the value of the fine gold you own because market price is calculated on fine weight. However, 22k coins can be preferred where extra hardness helps circulation or reduces softness issues during handling.
Common formats and who makes them
- Coins — typical denominations include 1 oz, 1/2 oz, 1/4 oz and 1/10 oz. Recognized mints: Royal Canadian Mint, Perth Mint, Austrian Mint, US Mint (American Eagle).
- Bars — sizes range from 1 g to 1 kg. Top refiners: PAMP Suisse, Valcambi, Credit Suisse, Johnson Matthey (historic), Engelhard, Sunshine Minting.
- Good Delivery bars — typically 400 oz and used by institutions; look for LBMA-recognized names.
Each format has verification features. Coins often bear sophisticated security measures (micro-engraving on Maple Leafs), while bars can include serial numbers, assay cards and tamper-evident packaging for brands like PAMP Suisse or Valcambi. If buying small bars (1–10 g), watch premiums: many tiny bars charge very high per-gram markups and may be worse value than fractional coins.
Examples from a buyer’s perspective:
- Anna, a safety-first saver, prefers 1/10 oz coins to keep a portable emergency stash in a household safe. She values divisibility and recognition from mints such as the Perth Mint.
- Ben, a long-term stacker, purchases 100 g bars from Credit Suisse and PAMP Suisse in an allocated vault; he aims to minimize premium per gram and optimize storage density.
Key purchasing tips: verify the product’s assay (serial numbers or assay cards), favor LBMA-listed refineries for large bars, and prefer coins from well-known sovereign mints for quick resale. See deeper product guidance at Pacific Precious Metals and an accessible overview at Physical Gold Insights. Ending insight: purity identifies fine weight; format changes your premium and practical use.
Premiums & Spreads: What you actually pay when buying and selling gold
Premiums and spreads make the biggest practical difference between coins and bars. This section explains the mechanics of premiums, how they change with size and format, and how to compute and compare offers using a clear formulaic approach. Expect concrete numerical examples and an example calculation for cost per gram.
Why premiums differ
Premiums over the spot price reflect minting costs, distribution, dealer margins and demand. Coins generally carry higher premiums due to minting complexity, legal tender backing, and collector demand. For example, a typical 1 oz bullion coin from a sovereign mint may carry a premium of $20–$60 over spot; fractional coins (1/10 oz) can be a higher multiple of spot per gram because fixed minting costs are spread over less gold.
Bars see a declining premium curve as weight increases. A 1 g or 5 g bar often has a high premium per gram; a 100 g or 1 kg bar will be much cheaper per gram. Brands affect premiums: PAMP Suisse, Valcambi and Credit Suisse command modest brand premiums due to assay and serial features that buyers trust. Less-known refinery products or unbranded generic bars may trade at slightly lower premiums but can be harder to resell quickly.
How to compare offers — formula and example
- Formula: Price per gram of fine gold = (Total price paid) / (grams × purity).
- Example A (coin): 1 oz coin price $2,050; fine grams = 31.1035 × .999 = 31.0724 g. Price per gram ≈ $2,050 ÷ 31.0724 ≈ $66.02/g.
- Example B (bar): 100 g .999 bar price $6,250; fine grams = 100 × .999 = 99.9 g. Price per gram ≈ $62.56/g.
In this example the bar costs ~5% less per gram — a material saving over large purchases. Always include shipping, VAT (where applicable), and insurance in your total price when calculating final per-gram cost.
Where spreads show up on resale:
- Dealer buy-back spread: dealers often buy at a lower price than they sell; check written buy-back terms.
- Local pawn or coin shop: may pay wider spreads for non-standard products.
- Auction or private sale: could narrow or widen spreads depending on buyer competition.
Why coin premiums swing more: marketplace demand for recognizable coins like the American Eagle, Canadian Maple Leaf or Krugerrand rises in times of retail panic. That demand increases the bid price in such moments, but also expands purchase premiums when supply is constrained. See discussions about coin price dynamics at APMEX Learn and market commentary at Daily Gold Price archives.
Practical buying rule: if your objective is to minimize cost per gram for a known holding period (5–10 years), prioritize bars in the 50–100 g to 1 kg range from trustworthy refiners. If you require frequent small sales or gifts, accept a higher premium for coins that will be easier to move. That is the key premium trade-off buyers must internalize.
Liquidity & Resale: How easy it is to turn gold into cash
Liquidity is often the deciding factor for small investors. This section explains where coins outperform bars, which bar sizes are acceptable for retail resale, and the practical steps to ensure smooth buy-backs. Examples cover walk-in dealers, vault providers and online platforms.
Coins: the liquidity champions
Sovereign coins like the Canadian Maple Leaf, US American Eagle, and the Perth Mint products are globally recognized. They are easier to sell at local coin shops, pawn outlets, and online market places. Fractional coins (1/10 oz, 1/4 oz) are especially useful for selling small amounts without touching your larger stack. For emergency liquidity, coins are usually the first choice.
- Pros: immediate walk-in resale; multiple small sales possible; recognizable hallmarks reduce verification friction.
- Cons: higher premiums; potential for numismatic swings if selling a collectible piece.
For a buyer like Anna (our safety-first saver), having a handful of 1/10 oz coins in the home safe provides portable value that can be converted quickly in case of sudden need.
Bars: good liquidity at certain sizes
Bars under 100 g often trade easily. One-ounce bars are also commonly accepted. As bar size rises to 250 g and 1 kg, the pool of buyers narrows; you may need to sell through a dealer with a vault network or an allocated storage provider. Institutional-sized Good Delivery bars (e.g., 400 oz) require wholesale channels. When buying high-weight bars, plan your exit route — prearranged buy-back with a vault operator or a dealer who handles large bars is essential.
- 50–100 g bars: solid balance between cost and resale practicality.
- 250 g–1 kg bars: best for long-term vault stacking; resale typically done through specialist dealers.
- 400 oz Good Delivery: wholesale market only.
Verification and fraud prevention matter for liquidity. Sellers and buyers use simple checks (weight, calipers, magnet) and pro checks (XRF, ultrasonic) for high-value items. Brands with assay cards or serial numbers (PAMP Suisse, Valcambi, Credit Suisse) travel better. Consider dealers that publish clear buy-back policies, and read independent guides such as GoldSilver for liquidity scenarios.
Key operational advice: if you expect to sell piecemeal, build a coin-heavy tranche. If you plan to hold and only occasionally sell in large blocks, concentrate on bars and ensure your storage provider has a resale network. That operational clarity prevents surprises at the moment of sale.
Storage, Insurance & Choosing by Objective — checklist and decision table
Storage and insurance are ongoing costs that can erode the benefit of lower premiums on bars. This section gives a step-by-step storage checklist, recommended storage types by objective, and a compact comparison table to guide a final allocation decision. It includes brand and dealer considerations and links to further reading.
Storage and insurance options
- Home safe: low ongoing cost but insurance may be limited by policy. Ideal for small emergency coin sets.
- Bank safety deposit box: moderate fee; restricted access hours; good for medium-term holdings but not ideal if you need fast physical access in a crisis.
- Allocated vault storage: annual fee (commonly 0.2–0.8% of asset value). Best for large bars and professional stacking. Providers often offer audit trails and insured storage.
Counterfeit risk and verification: for high-value bars insist on serial-numbered bars and assay cards (common for PAMP Suisse, Valcambi, and sometimes Credit Suisse). For coins, demand sealed tubes or capsules and verify mint marks. For high-security testing, dealers and vaults use XRF and ultrasonic testing to confirm composition. See a testing methods overview at History Tools and technical testing research referenced in industry archives like DailyGoldPrice.
Decision rules by objective (practical splits)
If you need a simple actionable allocation plan for a hypothetical €20,000 / $20,000 budget, consider these suggested mixes:
- Emergency liquidity (safety-first): 60% coins (1/10–1 oz), 40% small bars (20–100 g). Keep coins accessible in a home safe and small bars in a bank box.
- Long-term stacking (cost minimizer): 10% coins, 90% bars (100 g–1 kg) in allocated vault storage.
- DCA (regular small buys): fractional coins or 5–20 g bars to smooth premiums and avoid timing risk.
- Gifts/estate: coins for ease of transfer and sentimental appeal.
Comparison table — quick verdict on the four drivers:
| Criterion | Coins | Bars | Quick verdict |
|---|---|---|---|
| Purity | 22k–24k (piece-dependent) | Mostly 24k | Tie (value = fine gold) |
| Premium / gram | Higher | Lower (except very small) | Bars |
| Liquidity | Very strong | OK → weaker >100 g | Coins |
| Divisibility | Excellent | Poor | Coins |
| Storage efficiency | Good | Excellent (kg compact) | Bars (long term) |
Pre-buy checklist before you click buy:
- Spot vs total premium: confirm all fees, VAT, shipping and insurance are included.
- Authorized dealer: cross-check reviews, published buy-back terms and third-party ratings. Useful buying lists include Summit Metals and APMEX.
- Assay / serial: prefer products with assay cards or serial numbers for bars.
- Buy-back policy: get it in writing or via the dealer’s published terms.
- Resale path: identify 2–3 buyers (local dealer, online marketplace, vault provider).

Final operational insight: match the format to your exit plan before you buy; that simple discipline saves both premium and time when you sell.
Questions buyers often ask
Does 22k vs 24k matter? The market values fine gold, so pure fine weight matters more than the alloy. Choose 22k only for historical coins or if you need the harder metal for handling.
Why do coin premiums swing? Retail demand surges for recognizable sovereign coins during crises, pushing premiums up; supply constraints at mints can widen buy-sell spreads.
Best bar size for cost efficiency? For retail buyers, 100 g and 1 kg bars are among the best cost per gram options while remaining sellable to many dealers.

This closes the storage and allocation guidance — next, a short practical Q&A to clear common doubts.
Short Q&A
How should I split €20,000? A practical split: 50% bars (100 g–250 g), 40% coins (1/10–1 oz), 10% cash/near-cash metals. Adjust by liquidity needs.
Which brands should I favor? For bars: PAMP Suisse, Valcambi, Credit Suisse. For coins: Royal Canadian Mint, Perth Mint, and the US Mint. Historic refineries like Johnson Matthey, Engelhard and Sunshine Minting have market recognition too.
Final sentence: Decide by your exit plan first — liquidity needs mean coins, long-term cost efficiency means bars.
Frequently asked questions
Does 22k vs 24k affect resale value? No — resale markets price on fine gold weight. A 1 oz 22k coin’s resale value equals its fine gold content times the prevailing gold price, minus the dealer’s spread.
Why do coin premiums change so much? Coin premiums respond to retail demand, mint supply limits, and collectible interest. In spikes of retail buying, coins often trade at higher premiums than bars.
What is the best single bar size for a retail buyer? For most retail buyers, a 100 g bar is an efficient compromise: lower premium than small bars, more liquid than 1 kg bars.
How should I verify large bars? Insist on serial-numbered bars, assay cards and, for very high-value pieces, independent testing such as XRF. Work with an LBMA-recognized dealer or vault provider.
Where to learn more about taxes and storage? Tax rules vary — check local guidance at dedicated tax pages. For storage and insurance steps, consult storage & insurance guides linked earlier and consider an allocated vault for holdings above a few thousand dollars/euros.
