THE BULLION GUIDE
Start with what
you can verify.
Understand the product, the price and the terms of ownership. Small details make a meaningful difference.
Gold bars: read the specification
Cast bars are formed by pouring molten metal into a mould; minted bars are cut from rolled metal and finished with a stamped design. Compare the stated gross weight and fineness rather than appearance alone. Ask for the refiner’s details, invoice and any available assay documentation.
| Check | Why it matters |
|---|---|
| Gross weight | The total mass of the item, including any other metals. |
| Fineness | The share of the item that is gold, often expressed in parts per thousand. |
| Fine gold weight | Gross weight multiplied by fineness. |
| Premium | The amount added to the underlying metal value by the quoted seller. |
Bullion coins: gross versus fine weight
Some bullion coins are made from high fineness gold; others use an alloy for durability. A coin advertised as containing one troy ounce of fine gold can have a gross weight greater than one troy ounce. Use the issuing mint’s specification to avoid applying fineness twice.
For a calculator entry based on the coin’s stated fine gold content, choose “Fine gold weight / 100%”. For an entry based on its total gross weight, choose the correct fineness.
Custody: understand the relationship
Physical possession and ownership through a storage arrangement involve different practical questions. Review the provider’s contract, how your holdings are identified, the role of any sub-custodian, insurance exclusions, audit evidence and charges. An “allocated” description should be supported by the actual legal terms and records.
A buyer’s checklist
- Verify the seller’s legal identity and how you can contact them.
- Read the exact product specification, including fine gold content.
- Compare total purchase costs and the seller’s buyback terms.
- Check delivery arrangements or the custody contract and allocation records.
- Read insurance, audit and physical withdrawal conditions.
- Keep invoices and identifying documentation securely.
