How to Prepare for Selling Gold in Warsaw
Preparing your gold before a visit to a buying center protects two things: your money and your time. A few simple checks at home can move you from a vague quote to a transparent, document-backed offer that reflects today’s market price. Here is what to do before you walk through our door.
Check the purity of your gold
Most jewelry, bullion, and coins carry a hallmark stamp that tells you the gold content. In Poland, the common stamps are based on the parts-per-thousand system, so 585 means 58.5% pure gold by weight, and 750 means 75%. Finding this stamp first gives you a realistic baseline before you ever discuss price.
Common European gold hallmarks at a glance:
| Hallmark | Karat | Pure gold content |
|---|---|---|
| 999 | 24K | 99.9% |
| 916 | 22K | 91.6% |
| 750 | 18K | 75.0% |
| 585 | 14K | 58.5% |
| 500 | 12K | 50.0% |
| 375 | 9K | 37.5% |
| 333 | 8K | 33.3% |
If the stamp is faint or missing, do not write the item off. Professional buyers verify purity on-site with non-destructive XRF spectrometers and, for ambiguous cases, an acid test on a small filed area. For a deeper look at how this process works, see our gold valuation in Warsaw page.
Gather important documents
The minimum requirement is a valid government-issued ID — a Polish dowód osobisty, an EU national ID, or a passport. This is not a formality: Polish anti-money-laundering rules require registered gold dealers to identify the seller for any transaction.
Beyond ID, bring whatever paperwork you have for the items: jewelry receipts, certificates of authenticity, mint cards for bullion coins, or an old appraisal. None of these are strictly required, but they speed up valuation and can lift the offer on items where provenance matters, especially numismatic coins and signed jewelry.
Inspect the condition of your items
Wipe each piece with a soft, dry cloth so the hallmark is readable and the surface is clean. Skip polish, jewelry cleaners, or anything abrasive — for collectible coins especially, removing the natural patina can lower the offer rather than raise it.
Gold is priced primarily on weight and purity, so dents, missing stones, or broken clasps will not destroy the value. They can, however, affect items that would otherwise carry a numismatic or jewelry premium. If you are unsure whether something has collector value, bring it as-is and ask before you decide to sell.
Compare offers before you sell
Two buyers can quote very different prices for the same gram of 585 gold. The honest difference comes from three things: how close their buy price tracks the live LBMA spot rate, what spread they take for refining and risk, and whether they charge any hidden fees. The dishonest difference is everything else.
Before you walk into any office, check the live spot price in złoty — for example via the XE.com XAU-PLN converter — and ask each buyer to break down their quote per gram, per purity. A transparent operator will do this without hesitation.
Choose a trusted gold buyer
Look for a registered Polish company with a physical address, fixed opening hours, and reviews you can verify. A licensed kantor that also handles currency exchange is bound by the same NBP-registered framework, which adds an extra layer of accountability compared to a one-off pop-up buyer.
The right buyer should also explain its pricing rules up front, weigh your gold on a certified scale in front of you, and pay out the same day in cash or by transfer — your choice.
