100 g gold bar — LBMA-listed refiner, 999.9 fineness

A gold bar weighing 100 g at 999.9 fineness. It comes from a refiner on the LBMA Good Delivery List. At this weight the markup over the gold price is among the lowest in the minted bar range. In exchange divisibility is gone — it sells as a whole. One hundred grams is about 3.22 troy ounces — the heaviest minted bar we stock.

Technical specification

What sets this bar apart

• Refiner on the LBMA Good Delivery List — the bar is accepted in wholesale trade without re-assay.
• 999.9 fineness — of 1000 parts of the alloy, 999.9 are pure gold.
• Certificate inside the pack — the bar's serial number matches the number on the card, so no separate document is needed.
• Familiar format — gram bars are accepted for buyback without appraisal as long as the blister is intact.

What LBMA Good Delivery means

The London Bullion Market Association maintains a list of refiners whose bars are accepted in wholesale trade without re-assaying the metal. Admission requires a documented production history, minimum annual volumes and passing assay tests, and the status is reviewed periodically.

For a buyer the consequence is practical: a bar from a listed refiner needs neither proof of origin nor a costly appraisal on resale. This item is supplied from bars by various LBMA-listed refiners — which refinery arrives depends on availability in a given delivery, while weight, fineness and packaging remain identical.

Minted versus cast bars

Gram bars are punched and struck from rolled gold strip. The surface is smooth, the edges are straight, and every piece shares identical dimensions. Cast bars, common from a few hundred grams upwards, are made by pouring molten metal into a mould — hence their irregular, matte surface and slight variation in shape between pieces.

The difference shows up in price. Striking costs more than casting, so the markup over the metal price on gram bars sits higher than on large casts. In exchange a small bar is easier to sell as a whole, with no need to split a holding.

What to check before buying

The blister should stay closed. A bar taken out of its pack loses the link to its certificate and is sometimes valued lower on resale or has to be checked. Gold at 999.9 is soft — a fingerprint or scratch stays on the surface permanently.

In storage, avoid damp and pressure on the edges of the pack. The metal itself does not oxidise, but a cracked or lifted blister is the most common reason for a reduced buyback price on gram bars.

Frequently asked questions

How much pure gold is in a 100 g bar?

A fineness of 999.9 means that of 1000 parts of the alloy, 999.9 are pure gold. At 100 g the metal content is effectively the same as the total weight.

Does the bar come with a certificate?

Yes. The bar is sealed in a blister together with its certificate, and the serial number struck into the metal matches the number on the card.

Can the packaging be opened?

Technically yes, but it is not advisable. Outside the blister the bar loses the link to its certificate and is sometimes valued lower on resale or has to be checked.

Is VAT charged on gold bars?

In Poland gold meeting the conditions for bullion is exempt under Article 122 of the VAT Act. The exemption does not cover silver or platinum.

Do you buy bars back?

Yes, we buy back gold and silver. The buyback price follows the current metal quote and the condition of the packaging — an intact blister with certificate is valued highest.
