I've handled thousands of 100 gram gold bars across every major refinery over 15+ years in the bullion business. Here's what the spec sheets and product listings won't tell you.
Best for Volume Buyers
Argor-Heraeus is the bar I recommend to anyone stacking seriously. Founded in 1951 in Mendrisio, Switzerland, Argor is one of the three largest gold refineries in the world by volume and processes an estimated 400+ metric tons of gold per year. The premiums on Argor bars are consistently the lowest in this size category, the assay cards are clean and internationally recognized, and the Kinebar holographic variant adds a layer of authentication you genuinely want if you plan to resell internationally. I've seen Argor bars accepted without question at dealers in London, Dubai, and Singapore. For pure cost efficiency per gram, nothing beats it.
Overlooked Fact
Argor-Heraeus is part-owned by the Commerzbank group and has been an LBMA Good Delivery refinery since 1961 — one of the longest-tenured on that list. That institutional backing is why their bars trade without friction in any serious market.
Best for IRA & Gifting
Founded in 1977 in Ticino, Switzerland, PAMP Suisse is the world's leading independent precious metals refinery and the only refiner to stamp individual serial numbers on gold bars under 1 kg. Their Fortuna design has been in continuous production since 1979 and remains the single most recognized 100 gram gold bar sold globally. The Veriscan™ technology means any dealer with a scanner can verify authenticity in under 10 seconds — which directly protects your resale value.
If you're adding gold to a Self-Directed IRA, I always recommend PAMP first. Custodians know the brand, the paperwork processes cleanly, and you'll never face a verification dispute. The premium is slightly higher than Argor, but for IRA use or gifting, the brand recognition is worth every dollar.
Best for International Buyers
Valcambi's 100 gram bar is one of the most liquid products on the global bullion market. If you ever plan to sell outside the US, Valcambi bars are recognized and traded without friction at dealers across Europe, the Middle East, and Southeast Asia. The LBMA-approved hallmark on every bar is your insurance policy. Valcambi also produces a striking CombiBars version in other sizes — but the straight 100 gram bar is the play for buyers who prioritize liquidity above all else.
Best for Collectors Who Want Bullion
Scottsdale Mint's craftsmanship is genuinely impressive for a bullion product. The bar carries the same .9999 purity as any Swiss refinery bar but with a distinctly American aesthetic and attention to finish detail that most buyers notice immediately when they hold one. I recommend this to buyers who want a premium-looking product that still prices close to spot — the kind of bar you'd display before you vault it.
Every 100 gram bar we ship arrives in its original sealed assay packaging. Here's what to verify when your order is delivered:
Dealer Warning — Broken Seals
Never buy 100 gram gold bars that have been removed from their original assay packaging. The authentication value drops significantly, and most reputable dealers — including BOLD — apply a lower buyback value to broken-seal bars. Keep the seal intact until you are ready to sell or transfer to a vault.
One of the most overlooked advantages of the 100 gram size is its resale mechanics. Here's what matters when it comes time to sell:
Higher per-gram cost on the way in; less recaptured on exit.
Low per-gram premium in; near-spot buyback out. Maximum liquidity.
BOLD Precious Metals offers competitive buyback pricing on all 100 gram gold bars we carry. Because these bars come from LBMA-certified refineries with individual serial numbers and assay cards, we process buybacks quickly — no third-party verification delays, no prolonged authentication holds.

At current spot prices, a single 100 gram gold bar represents a $6,500–$7,000+ asset. Here's how serious buyers protect it:
This size is purpose-built for three types of buyers — and it's the wrong choice for almost no one in that group.
Buyer Type 1
You've already bought 1 oz gold bars and coins. You've run the math and realized the per-gram premium on smaller products is a drag on your return. The 100 gram bar is the natural step up — lower cost per gram, same .9999 purity, same global liquidity.
Buyer Type 2
You're building a Self-Directed IRA and need IRS-compliant gold (.9999 minimum fineness, from an approved refinery). Every 100 gram bar BOLD sells meets these standards. We coordinate directly with your IRA custodian on delivery to an approved depository.
Buyer Type 3
You're not trading. You're storing value across decades. A 100 gram bar — sealed in its assay card, held in a private vault — is one of the most efficient formats for long-term gold ownership. Low overhead, maximum density, no counterparty risk.
The price changes daily with the live spot price of gold . A 100 gram bar contains 3.215 troy ounces of .9999 fine gold, so the melt value equals 3.215 × the current spot price. On top of that, you pay a refinery premium — typically the lowest per-gram premium available in the retail bullion market at this weight.
Yes. All 100 gram gold bars meet IRS minimum fineness requirements of .9995 or higher (most are .9999 fine) and are produced by LBMA-accredited refineries. You'll need to work with an IRS-approved custodian and depository when setting up a Self-Directed IRA.
It depends on your goal. For lower premiums, many buyers choose Argor-Heraeus bars. For widely recognized brands and resale liquidity, PAMP Suisse or Valcambi Suisse bars are commonly preferred. All major LBMA-accredited refiners produce reliable investment-grade gold bars.
Check the serial number against the assay card, verify the weight using a precise digital scale, and confirm the refinery hallmark. Many modern gold bars also include authentication tools such as serial verification or digital scanning features provided by the manufacturer.
Yes. Most bullion dealers offer buyback services for standard 100 gram gold bars at competitive market prices. Bars from recognized LBMA-certified refiners typically receive faster verification and strong resale liquidity.
A 100 gram gold bar contains approximately 3.215 troy ounces, while a 3 troy ounce bar contains exactly 3 troy ounces (about 93.3 grams). The 100 gram format is more widely produced and recognized globally.
Many bullion dealers offer free insured shipping on qualifying orders that include 100 gram gold bars. Orders are typically packaged discreetly and insured to their full value during transit.
