Gold hallmarks explained
Hallmarks can provide useful information on certain gold items, especially jewellery, but they are not the only check for bullion.
Last reviewed: 2026-05-23
What hallmarks show
A hallmark can indicate precious metal content and assay office details. The exact marks depend on the item and rules that applied at the time.
Bullion checks differ
Bullion products often rely on mint marks, serial numbers, certificates, packaging, dimensions, and dealer verification rather than jewellery-style hallmarks alone.

FAQs
Does every gold item have a hallmark?
No. Exemptions and product differences exist, and some bullion products are marked differently from jewellery.
Can a hallmark prove value?
It can help with identification, but value also depends on weight, purity, condition, market price, and buyer policy.
Can fake marks exist?
Yes. Readers should not rely on one mark alone when authenticity matters.
