A 100 gram gold bar holds 3.21507 troy ounces of gold and sits neatly between the one ounce coin and the kilo bar. It gives you real weight at a low premium per ounce while staying easy to store and resell, which is why almost every major refiner and government mint makes one.
That leaves buyers with a genuine choice. Since the gold content is identical from bar to bar, the decision comes down to four things: the format, the security features, the packaging, and the premium. Here is how the leading 100 gram bars stack up.
What they share
Every bar below contains 100 grams of gold, equal to 3.21507 troy ounces, at .9999 fine (24 karat) purity. Each is priced on the live gold content plus a dealer premium, and most ship sealed in a tamper-evident assay card with a matching serial number. What separates them is everything else.

Valcambi: three ways to buy 100 grams
Valcambi is an LBMA Good Delivery refiner, and it offers the 100 gram size in three forms. The minted bar is the standard: crisp finish, sealed assay, serial number, competitive premium. The cast bar is poured into a mold rather than pressed, giving it a rustic look and usually the lowest premium of the three, since cast bars cost less to make. The CombiBar is the interesting one: scored into 100 detachable one gram sections and about as thick as a credit card, so you can break off a gram to sell or gift without cashing in the whole bar. That flexibility costs a slightly higher premium. Our Valcambi gold bars guide covers the full range.
PAMP Suisse: minted or hand-poured
PAMP is the brand many buyers picture first. The Lady Fortuna bar ships in a CertiPAMP assay card and supports Veriscan, PAMP’s system for verifying a bar against its microscopic surface pattern by app or scanner. It is highly liquid and easy to resell anywhere. The poured bar holds the same gold in a hand-poured finish that some collectors prefer. See how to verify a PAMP Suisse gold bar for the details.
Argor-Heraeus KineBar
The KineBar embeds a Kinegram, a holographic image struck into the bar’s surface that is very hard to fake. If anti-counterfeiting is your priority, the KineBar builds it into the bar rather than the packaging. Argor-Heraeus is a Swiss refiner owned by Germany’s Heraeus group.
Rand Refinery
The Rand Refinery bar comes from South Africa’s Rand Refinery, which refines the gold behind the Krugerrand. It ships new in assay, sealed with a matching serial number straight from the refiner, and often prices competitively.
RCM and the Royal Mint
Two bars come from national mints. The Royal Canadian Mint bar ships sealed in assay with a serial number, and the Royal Mint Britannia bar carries the Britannia design from the UK’s Royal Mint. If you are choosing between them, note that these are two separate national mints, one Canadian and one British.
How to choose
The gold is the same, so pick for what you value. For the lowest premium, look at the Valcambi Cast and the Rand Refinery bars. For resale and recognition, PAMP Lady Fortuna and the Valcambi minted bar are hard to beat. For divisibility, only the CombiBar breaks into grams. For built-in security, the KineBar and PAMP’s Veriscan bars.
The price you actually pay depends on the dealer, so compare live prices on each bar and sort by the premium over spot. Browse the full range on our gold bars hub, and see our gold bars buyer’s guide for how the 100 gram size compares to other formats.
