Why Buy Gold Bars Over Coins?
Gold bars exist for one reason: lower premiums. A 1 oz gold bar typically costs 2-4% over spot, compared to 4-7% for sovereign coins. At $4,795/oz gold, that 2-3% difference saves $96-144 per ounce. Scale that to a 10 oz purchase and you are keeping $960-1,440 more of your capital in actual gold rather than minting and distribution costs.
The trade-off is straightforward. Bars lack the government-backed face value and legal tender status of sovereign coins. They are not IRA eligible unless produced by an LBMA-accredited or COMEX-approved refiner (most on this list qualify). And some bars carry slightly wider buy-sell spreads than the most popular coins.
This guide ranks the top gold bar manufacturers, compares sizes from 1 gram to 1 kilogram, and breaks down the cast vs minted decision with real premium data.

1. PAMP Suisse
The most recognized name in gold bars worldwide. PAMP (Produits Artistiques Metaux Precieux) operates one of the largest precious metals refineries in Switzerland, processing over 450 tonnes of gold annually.
Key products:
- Lady Fortuna bar (1g to 1kg): the iconic design featuring the Roman goddess of fortune. The single most recognizable gold bar design in the world.
- Cast bars (50g, 100g, 1kg): lower-premium alternatives to the minted Fortuna line.
- Veriscan technology: a proprietary anti-counterfeiting system that maps each bar’s unique surface topology. Dealers with Veriscan readers can verify authenticity in seconds.
Typical premiums (1 oz minted bar): 3-5% over spot. The Lady Fortuna design commands a slight premium over plain bars from other refiners. At $4,795 gold, expect $144-240 above spot.
Why PAMP ranks first. Brand recognition drives resale value. PAMP bars sell faster and at tighter spreads than bars from lesser-known refiners. The Veriscan system provides the strongest anti-counterfeiting protection available on any gold bar. LBMA Good Delivery accreditation ensures the bar meets international purity and assay standards. Every bar ships in a CertiPAMP assay card with a unique serial number.
Considerations. You pay a brand premium. PAMP bars cost $15-40 more per ounce than equivalent Asahi or generic LBMA bars. If raw cost matters more than brand, other options deliver more gold per dollar.
Best for: Buyers who value brand recognition, gift-giving, resale in international markets.
2. Valcambi
Switzerland’s largest gold refiner by volume, processing over 1,600 tonnes of precious metals annually. Valcambi is owned by Global Gold Refining and operates under strict Swiss regulatory oversight.
Key products:
- Standard minted bars (1g to 1kg): clean, minimalist design with assay certificate.
- CombiBar: a 50g or 100g bar scored into 1g segments that can be individually broken off and used. Combines bulk pricing with fractional flexibility.
- Green Gold bars: produced from responsibly sourced gold under the Swiss Better Gold Initiative.
Typical premiums (1 oz minted bar): 2-4% over spot. Valcambi bars consistently undercut PAMP by $10-25 per ounce. The CombiBar carries a slightly higher premium due to additional manufacturing complexity.
Why Valcambi ranks second. The CombiBar is a genuinely innovative product. A 50g CombiBar gives you fifty 1g segments in a single package, purchased at a per-gram premium well below what you would pay for fifty individual 1g bars. For buyers who may need fractional gold (gifts, small trades, emergency liquidity), the CombiBar is unmatched.
Standard Valcambi bars offer Swiss refining quality at lower premiums than PAMP. LBMA accredited, serial numbered, and widely recognized by dealers globally.
Considerations. Lower brand recognition than PAMP in retail markets. The CombiBar’s scored segments can separate unintentionally if mishandled. Once broken apart, individual segments lose the assay card association, potentially reducing resale value.
Best for: Cost-conscious buyers, fractional flexibility (CombiBar), environmentally conscious investors (Green Gold line).
3. Royal Canadian Mint (RCM)
The same mint that produces the Gold Maple Leaf coin also manufactures gold bars of exceptional quality. RCM bars carry the weight of a G7 government mint behind them.
Key products:
- Minted bars (1 oz, 10 oz): .9999 purity, serialized, in assay packaging.
- Sealed and serialized with RCM’s advanced security features.
- Available in fewer sizes than Swiss refiners (primarily 1 oz and 10 oz for retail).
Typical premiums (1 oz minted bar): 2-4% over spot. Competitive with Valcambi, often slightly below. The 10 oz bar offers 1.5-3% premiums.
Why RCM ranks third. The Royal Canadian Mint’s reputation for purity is unassailable. Every RCM gold bar is .9999 fine, matching the Maple Leaf coin standard. The mint’s bullion DNA program assigns a unique digital certificate to each bar, traceable through the supply chain. As a sovereign mint, RCM products carry implicit government backing that private refiners cannot match.
Considerations. Limited size range compared to PAMP or Valcambi. RCM does not produce bars smaller than 1 oz for the retail market, ruling them out for gram-weight buyers. Distribution in Europe and Asia is thinner than Swiss products.
Best for: Buyers who want sovereign mint backing on a bar product, Canadian investors, purity purists.
4. Perth Mint
Australia’s oldest operating mint (established 1899) produces gold bars that are recognized and traded globally, with particularly strong distribution in Asia-Pacific markets.
Key products:
- Minted bars (1 oz, 10 oz): .9999 purity, individually sealed with assay certificate.
- Cast bars (1 oz, 10 oz, 1kg): lower-premium option with the distinctive Perth Mint swan logo.
- Kangaroo-branded minted bars with the annual kangaroo design.
Typical premiums (1 oz minted bar): 3-5% over spot. Perth Mint bars carry slightly higher premiums in North American and European markets due to shipping costs from Australia. In Asian markets, premiums are more competitive.
Why Perth ranks fourth. Perth Mint’s reputation in the Asia-Pacific region is comparable to PAMP’s in Europe. For investors who may sell into Asian markets (Singapore, Hong Kong, Japan), Perth Mint bars are the preferred product. The mint is owned by the Western Australian government, providing sovereign backing similar to RCM.
Considerations. Higher premiums in Western markets due to distribution costs. The Kangaroo-branded bars carry a slight design premium over generic Perth Mint bars. Less available from US and European dealers compared to Swiss or Canadian products.
Best for: Asia-Pacific investors, buyers who value government-owned mint backing, Australian residents.
5. Asahi Refining
Asahi acquired Johnson Matthey’s gold and silver refining operations in 2015, inheriting one of the most established names in precious metals. Asahi now operates major refineries in Salt Lake City (US) and Brampton (Canada).
Key products:
- Minted bars (1 oz, 10 oz): clean, functional design. Serial numbered with assay cards.
- Cast bars: available in larger sizes for institutional buyers.
- Formerly Johnson Matthey branded bars are still traded actively on the secondary market.
Typical premiums (1 oz minted bar): 2-3% over spot. Consistently among the lowest premiums available on name-brand gold bars. At $4,795 gold, expect $96-144 above spot.
Why Asahi ranks fifth. Pure value. Asahi bars deliver LBMA-accredited gold at the lowest premiums of any major brand on this list. The North American refining operations mean lower distribution costs for US and Canadian buyers. The Johnson Matthey heritage provides decades of trust and recognition in the dealer community.
Considerations. Lower brand recognition with retail buyers compared to PAMP or Perth Mint. The Asahi name is newer (2015 acquisition), and some buyers are less familiar with it. Resale premiums may be slightly thinner than PAMP or Valcambi bars.
Best for: Budget-focused buyers, those who prioritize gold content per dollar over brand prestige.
6. Credit Suisse
Credit Suisse gold bars were a staple of the bullion market for decades. Following Credit Suisse’s acquisition by UBS in 2023, new production has diminished, but enormous quantities of existing bars remain in circulation.
Key products:
- Classic minted bars (1 oz, 10 oz): simple design with the Credit Suisse logo, serial number, and assay card.
- Static weight bars (1g to 1kg): various sizes for different price points.
Typical premiums (1 oz, secondary market): 2-4% over spot. Credit Suisse bars trade at competitive premiums due to abundant supply on the secondary market.
Why Credit Suisse ranks sixth. The sheer volume of Credit Suisse bars in circulation means they are easy to find on the secondary market, often at premiums comparable to or below current-production bars. These bars were refined by Valcambi and Metalor, both LBMA-accredited refiners, so purity and quality are not concerns. Every major dealer recognizes and buys them without hesitation.
Considerations. New production is limited following the UBS acquisition. Some buyers are confused by the Credit Suisse brand status, though this has no bearing on the gold content or value. Over time, secondary market supply will thin as bars are absorbed into long-term holdings.
Best for: Secondary market bargain hunters, buyers who want Swiss-refined gold at competitive premiums.
Cast vs Minted: Which Bar Type Should You Buy?
Gold bars come in two production styles, and the choice affects your premium, appearance, and resale experience.
Minted Bars
Produced by cutting gold blanks from a rolled strip, then stamping them with the refiner’s design in a press. The result is a precise, mirror-finish bar with sharp edges and detailed artwork.
- Premiums: Higher, typically 1-2% above cast bars of the same size.
- Appearance: Clean, polished, professional. Better for gifting or display.
- Packaging: Usually sealed in assay card packaging with serial number and purity certificate.
- Counterfeiting: Harder to fake convincingly due to the precise finish and packaging.
Cast Bars
Produced by pouring molten gold into a mold or by using a continuous casting process. The result is a more rustic bar with a rougher surface texture and slightly irregular edges.
- Premiums: Lower. The simpler production process reduces manufacturing costs.
- Appearance: Industrial, organic. Each bar is slightly unique in surface texture.
- Packaging: Often shrink-wrapped or loose, without elaborate assay packaging.
- Sizes: Cast bars dominate the larger size categories (100g, 1kg) where the manufacturing cost savings are most meaningful.
Verdict: Buy minted bars in smaller sizes (1 oz and under) where the premium difference is small and the assay packaging adds authentication value. Buy cast bars in larger sizes (100g, 1kg) where the premium savings are substantial and authentication relies more on weight, dimensions, and refiner stamps.
Gold Bar Sizes: Premium Comparison
Premiums decrease as bar size increases, reflecting the fixed manufacturing cost spread over more gold:
| Size | Typical Premium | Dollar Premium (at $4,795/oz gold) | Best For |
|---|---|---|---|
| 1 gram (0.032 oz) | 15-30% | $23-46 | Gifts, micro-investing |
| 5 grams (0.161 oz) | 8-15% | $62-116 | Small additions |
| 10 grams (0.322 oz) | 5-10% | $77-154 | Moderate budget |
| 1 oz (31.1g) | 2-5% | $96-240 | Standard investment size |
| 10 oz (311g) | 1.5-3% | $720-1,440 | Serious investors |
| 100 grams (3.22 oz) | 2-4% | $190-380 | Metric standard |
| 1 kilogram (32.15 oz) | 1-2.5% | $960-2,400 | Large-scale accumulation |
The sweet spot for most investors is the 1 oz bar. It offers low premiums, broad dealer acceptance, easy storage, and sufficient liquidity for most selling scenarios. The 10 oz bar reduces premiums further but requires a larger capital commitment ($30,000+) and may be harder to sell in partial quantities.
Gram-weight bars (1g, 5g) carry disproportionately high premiums and are generally poor investment vehicles. They make sense as gifts or as a way to start buying gold with minimal capital.
What Is LBMA Accreditation and Why Does It Matter?
The London Bullion Market Association (LBMA) maintains a Good Delivery List of approved refiners. To earn and retain accreditation, a refiner must meet strict standards for assay accuracy, bar quality, and responsible sourcing.
LBMA accreditation matters for three practical reasons:
- IRA eligibility. Gold bars in self-directed IRAs must be .995+ purity and produced by an LBMA-accredited or COMEX-approved refiner.
- Resale liquidity. LBMA bars are accepted by every major dealer worldwide without additional assay or verification. Non-LBMA bars may require third-party testing before a dealer will purchase them.
- Counterfeiting protection. LBMA refiners undergo regular audits and maintain traceable production records, reducing the risk of fraudulent products entering the supply chain.
Every manufacturer on this list is LBMA accredited. If you are considering a bar from a refiner not mentioned here, verify their LBMA status before buying.
How to Verify a Gold Bar Is Authentic
Gold bar counterfeiting is a real risk, particularly with bars purchased outside authorized dealer networks. Key verification steps:
- Weight. Use a precision scale (0.01g accuracy). A 1 oz gold bar should weigh 31.103g. Any deviation beyond 0.05g is suspicious.
- Dimensions. Measure length, width, and thickness with calipers. Compare to the manufacturer’s published specifications.
- Serial number. Verify against the manufacturer’s database if available (PAMP Veriscan, RCM Bullion DNA).
- Sigma testing. A Sigma Metalytics Precious Metal Verifier measures electrical conductivity, which is specific to gold’s .999+ purity. This test is non-destructive and takes seconds.
- Assay card. Genuine bars from major refiners ship in sealed assay packaging. Inspect the card for print quality, holographic elements, and serial number matching.
Buy from established dealers with authenticity guarantees and return policies. Check our dealer reviews for trusted sources.

Frequently Asked Questions
Are gold bars a better investment than gold coins?
Gold bars offer lower premiums, meaning more gold per dollar. Gold coins offer government backing, legal tender status, and broader recognition. For pure cost efficiency, bars win. For liquidity and ease of resale (especially in smaller quantities), coins often outperform. Most investors benefit from holding both. Read our bars vs coins comparison for the full analysis.
What size gold bar should I buy?
The 1 oz bar is the optimal size for most individual investors. It balances low premiums (2-5%) with strong liquidity and manageable cost ($3,000+ per bar). Larger bars (10 oz, 1 kg) offer lower premiums per ounce but require significantly more capital and may be harder to sell quickly. Avoid gram-weight bars for investment purposes, as their 15-30% premiums are excessive.
Can I put gold bars in an IRA?
Yes, provided the bar is .995+ purity and produced by an LBMA-accredited or COMEX-approved refiner. All six manufacturers in this guide qualify. The bar must be stored at an IRS-approved depository. Home storage is not permitted for IRA-held gold. Your IRA custodian will coordinate purchase and storage.
How should I store gold bars at home?
A quality home safe (fireproof, bolted to structure) is the minimum requirement. Keep bars in their original sealed packaging when possible. Document serial numbers and store records separately from the physical gold. Consider supplemental insurance, as standard homeowners policies typically cap precious metals coverage at $200-1,000. Read our gold storage guide for complete options.
Is it safe to buy gold bars online?
Buying from established, reviewed online dealers is generally safer than local shops, which may have limited inventory and higher markups. Reputable online dealers offer authenticity guarantees, return policies, insured shipping, and competitive pricing. The key is buying from the right dealer.
