Gold bars come in many different shapes and sizes, and buying in bulk saves you money.
At the most expensive end of the gold bar price scale, one-gram "novelty" gold bars are minted for the gift market. Often coated in plastic, these tiny gold bars cost at least twice the value of their gold bullion content.
Cheapest of all, in contrast, are the 400-ounce (12.4kg) "Good Delivery" gold bars held by central banks, and traded by professional bullion dealers in London, center of the world's 24-hour gold market.
It's the live dealing in these 400-oz gold bars, along with the trade in Comex gold market-approved bars in New York (100 oz), that creates the spot gold price you see quoted on the internet and in your newspaper.
There are more than 30 types of gold bar circulating in the world's regional gold markets today. In value terms, the most heavily traded gold bars – with the largest ready market, open 24 hours a day, five days a week – are the Good Delivery gold bars bought and sold through dealers working in London.
Sixty-three active gold refineries, all closely monitored and approved by the London Bullion Market Association, make around 150,000 of these 400-ounce gold bars each year. That's worth some $102 billion at current prices (Jan. '13).
In the smaller, local gold markets of India, Singapore and the Middle East, the most widely traded gold bar is the "ten tola" bar. Rarely stamped with a serial number and weighing 3.75 oz (117g) each, two million of these "TT" gold bars are cast or minted each year.
The most popular gold bar in China is the "five tael biscuit" bar (6 oz; 187g). Manufactured in Hong Kong, five-tael gold bars are approved and recognized by the Chinese Gold & Silver Exchange, now in operation for almost a century.
Outside Asia, the most popular gold bar sold to private investors for personal storage is the kilobar (1000g; 32.15 ounces). More than a million of these gold bars are manufactured each year, most often in Switzerland.
The leading gold-bar refineries also make vast quantities of one-ounce gold bars every year – and just like the kilobar, these gold bars are widely promoted as a cost-effective route to gold investment.
But these smaller gold bars, although they're cheaper than gold coins, don't come without significant drawbacks.
Buying Gold bars is almost always cheaper than buying the same weight in gold coins – and the bigger each bar, the lower the cost by weight.
Depending on your local tax regime, you can reduce or completely avoid paying sales tax (VAT) by buying gold bars instead of coins, too. Your savings will also depend on the quality (or "fineness") of the gold bars you buy.
Trading Good Delivery gold bars – guaranteed to be of 99.5% fine or above – can then cut your tax bill again in many countries, because these 100- and 400-ounce gold bars are defined as investment gold and eligible for personal retirement plans. Good Delivery gold bars reduce your costs further still by retaining main market deliverable status. Depending on your point of view the elimination of private possession and insurance arrangements is also a plus.
Smaller gold bars bought and stored at home, on the other hand – or even kept in a bank safety deposit box – present three big drawbacks.
Specialist gold-bar storage programs – such as gold pool accounts and certificate schemes – offer to help cut out the hassle of taking physical possession. This can certainly help reduce the premiums you pay to buy gold and sell. But their storage fees still run up to 1.5% per year.
That's a significant charge for owning gold bars – a passive investment that pays you no interest. There is a much cheaper route, however, into buying gold and owning it outright.
To retain Good Delivery status, the big 400-ounce bars of gold traded by refineries, central banks, wholesalers, bullion banks and professional dealers must remain inside secure, recognized gold bullion vaults.
Take these gold bars out of market-approved storage – even to store at your bank – and they break the chain of integrity that guarantees each bar's gold to the next buyer.
It's the integrity of Good Delivery gold bars that ensures maximum resale when you come to sell. But until recently, private investors couldn't easily access this market unless they were able to buy a whole 400-oz bar. Nor could they arrange market-approved storage unless they owned five big bars or more.
At BullionVault, however, you can now buy gold in amounts as little as one gram at a time. Stored in market-approved gold bar facilities, your gold will retain its maximum resale value. Storage fees for owning a portion of these big gold bars run as low as 0.12% per year, with insurance included.
