Gold Bar

Nothing gets you closer to owning gold in its purest form than a gold bar. Where gold coins come with a legal-tender face value and often a collector mark-up, bars carry neither — what you pay tracks almost entirely the prevailing gold price and the bar's fine weight. That lean pricing is why private savers, central banks and institutions alike reach for the bar as the cheapest route into physical investment gold.

Two ways to make a bar

Bar production splits into two basic techniques:

Cast bars start as molten fine gold poured into a mould and left to set at its own pace. What you get is that distinctive, slightly irregular crystalline face and a rough-hewn look. Because casting costs less, these tend to appear in the heavier weight brackets, from 50 g on up.

Minted bars (sometimes called coin bars) begin as a rolled strip of gold that is punched into blanks and then run through a minting press, which impresses the fineness, weight, serial number and maker's mark. The glossy, mirror-like face and crisp lettering lend them a more upmarket feel. They cost more to make, so the premium (agio) climbs noticeably on the small pieces (1 g – 10 g).

The size range

Purity and fineness

The overwhelming majority of today's investment bars are struck in 999.9‰ fine gold — the grade known as "four nines" or 24 carat. Put plainly, every 1,000 weight-parts hold at least 999.9 parts of pure gold, with only unavoidable trace contaminants making up the tiny remainder.

Fine weight = gross weight × (fineness ÷ 1000)

Example: 100 g bar at 999.9 ‰
→ 100 g × (999.9 ÷ 1000) = 99.99 g fine gold

LBMA Good Delivery – the global benchmark

For high-volume bars, the pre-eminent international yardstick is LBMA Good Delivery accreditation from the London Bullion Market Association. To earn it, a bar has to satisfy every one of these conditions:

• A fineness no lower than 995.0 ‰
• A weight in the 350 to 430 troy ounce band (roughly 10.9 – 13.4 kg)
• Legible marking: serial number, maker's mark, weight, fineness, year
• Manufacture by a refinery on the LBMA's accepted list

Names you are most likely to see on that list include Heraeus, Umicore, PAMP Suisse, Valcambi and Argor-Heraeus.

Verifying that a bar is genuine

Since gold's high density means a fake will usually betray itself on weight or size, a few straightforward checks can give a bar a sanity test:

1. A weight check on a calibrated precision scale (typical tolerance ± 0.05 g)
2. A density measurement by the Archimedean method (gold: 19.32 g/cm³; tungsten sits close but conducts heat differently)
3. A magnet test — being diamagnetic, gold ignores even a strong magnet
4. Ultrasound or X-ray fluorescence analysis (XRF) where professional testing is called for

How Ireland taxes gold bars

Any gold bar of at least 995‰ fineness ranks as investment gold and is free of VAT at purchase under the VAT Consolidation Act 2010 (Schedule 1) together with the EU VAT Directive 2006/112/EC. That marks gold out clearly from silver, platinum and palladium, all of which attract the standard Irish VAT rate of 23% when bought.

Selling at a gain works differently: for a private individual in Ireland, the profit is subject to Capital Gains Tax at 33%, once the annual personal exemption of EUR 1,270 has been applied. There is no relief for how long you hold — time of ownership does nothing to cut the bill. Germany takes the opposite line, where a gain turns income-tax-free after a one-year holding period under Paragraph 23 EStG. Note: this is not tax advice — for your individual situation please consult a qualified adviser.

When precious metals are bought for cash, dealers carry anti-money-laundering duties from a threshold of EUR 10,000 under the Criminal Justice (Money Laundering and Terrorist Financing) Act 2010, the point at which identity verification kicks in.

Premium and value for money

As bars get smaller, the percentage premium (agio) over the bare spot price climbs. A 1 g bar might carry a 20–35% mark-up, whereas a 1 kg bar usually sits at just 1–3%. So investors watching costs gain by buying in the largest denominations they sensibly can — provided liquidity and storage permit. The live gold rate and the resulting figures are in the gold calculator.

Where to keep them

You can hold gold bars at home in a safe, ideally bricked in or bolted down, lodge them in a bank safe-deposit box, or place them with a specialist precious metals depository (a bonded warehouse). Cost and risk differ across all three. If you keep them at home, take out household cover that names precious metals explicitly.

The short version

At 999.9‰ fineness, gold bars are the purest form of physical gold investment, and in the larger sizes the most economical too — VAT-free in Ireland, hit with 33% Capital Gains Tax on any disposal gain regardless of holding time, and still checkable for authenticity with tried-and-tested methods.
