Gold in a Small Format
This is 5 grams of .9999 gold, struck by the Perth Mint and sealed in a serial-numbered assay card. It is about a sixth of a troy ounce, one of the smallest gold bars that still ships with full mint certification.
The Perth Mint
The Perth Mint is Australia’s government mint, founded in 1899 and owned by the state of Western Australia. Its swan hallmark is one of the most recognized marks in gold. The bar leads with that swan over three stamped lines, 99.99% PURE GOLD 5 GRAM, and the back is tiled with leaping kangaroos. It is sealed in the mint’s black CertiCard with a matching serial number printed on the card.
What a Small Bar Costs You
Say it straight: a 5 gram bar carries a higher premium per gram than a 1 oz bar. The mint spends nearly as much cutting dies, striking and certifying a small bar as a large one, and that cost spreads across less gold. Every small format runs a higher premium per ounce, from any mint. Nobody buys a 5 gram bar to get the cheapest gold in the room.
For a bar this valuable in a package this small, keep the seal intact if you can. The card, its serial number and the tamper-evident case are how a buyer verifies it without opening anything. Break the seal and resale gets slower and the offer usually softer.
Why It Still Holds Up
Set the size aside and it is 5 grams of .9999 fine gold from a sovereign mint, sealed with a serial that matches the certificate. It is IRA eligible, it stores in a wallet or a small safe, and it lets you buy gold without a four-figure outlay or set one aside as a gift.

Perth Mint 5 Gram Bar FAQ
How much gold is in a 5 gram bar?
Five grams, which is 0.161 troy ounces, at 99.99 percent purity. That is close to a sixth of a full troy ounce.
Why does a 5 gram bar cost more per gram than a 1 oz bar?
The cost of making and certifying a bar barely changes with its size, so on a small bar that fixed cost is spread over less metal. Every fractional gold product, from any mint, carries a higher premium per ounce than the one ounce version.
Should I keep it sealed in the assay card?
Yes, if you can. The card, the serial number and the tamper-evident case are what a future buyer checks. Taking the bar out does not change the gold, but it makes resale slower and can cost you on the offer.
Is the Perth Mint 5 gram gold bar IRA eligible?
Yes. At 99.99 percent fine gold from a sovereign mint it meets the fineness a precious metals IRA requires, and our Specifications tab lists it as IRA eligible.
Is the bar minted or cast?
Minted. It is struck with the Perth Mint swan hallmark and the stamped weight and purity, then sealed in the assay card.
