Before selling platinum, separate bullion, jewelry, potentially collectible pieces and mixed scrap. Record marks, condition, components, gross and net weight, likely fineness, a documented reference price, and each buyer's test and settlement terms. A calculator can show a transparent metal-content model; it cannot set the price a buyer must pay.
A platinum-selling workflow
- Inventory and photograph the item. Preserve hallmarks, packaging, receipts, serial numbers, maker details and condition before an inspection or shipment.
- Classify it before calling it scrap. Keep recognized bullion, coins, signed jewelry, stone-set jewelry, watches, dental or industrial material, and mixed lots separate.
- Check for value above metal content. A named maker, a desirable design, gemstone setting, historical piece or recognizable bullion product may be worth more intact than a melt estimate.
- Establish a usable weight and fineness. Gross weight may include stones, steel mechanisms, solder or other non-platinum material. Treat a stamp as a starting point for testing, not a final settlement result.
- Capture a reference quote. Record the source, currency, price type, unit, timestamp and time zone. This site does not publish a live platinum price.
- Model contained-metal value. Keep the price, net weight, fineness and any payout assumption visible in the platinum value calculator.
- Request written, comparable terms. Ask how the buyer sets payable weight, verifies content, locks price, deducts costs and handles a declined transaction.
- Compare what you receive. Use final net proceeds, timing, shipping or insurance, return policy and risk—not a headline percentage alone.
Sort platinum by the question a buyer must answer
| What you have | What to establish first | Possible route to compare |
|---|---|---|
| Recognized platinum bar or coin | Exact product, authenticity, fine weight, condition and current resale demand | Several bullion dealers that quote a product buyback |
| Signed, antique or distinctive jewelry | Maker, marks, period, design, condition, stones and provenance | Estate-jewelry specialist, qualified appraiser or appropriate auction |
| Plain platinum jewelry | Payable platinum-bearing weight, measured fineness, stones and non-metal components | Multiple transparent precious-metal buyers |
| Mixed professional or industrial material | Ownership, safe handling, representative sampling, assay, recovery and settlement terms | A specialist refiner or buyer equipped for that material |
The table is a matching exercise, not a recommendation for a particular business. A bullion buyer may understand a product premium that a scrap buyer does not. An intact ring or signed object can lose evidence and resale value if it is altered before the right market is considered.
Use marks and appearance carefully
Platinum jewelry is often marked with a fineness or platinum notation, but mark formats vary by place and period. A number such as 950 can be meaningful only with the surrounding mark and context. Color, density and a visual inspection do not reliably identify an alloy; white gold, palladium alloys, rhodium-plated pieces and other white metals can look similar.
Photograph every mark before cleaning or repair. Do not file, acid-test, heat or dismantle a potentially valuable item merely to make an online estimate. A buyer's final payable content can differ from a visible stamp after a suitable test or assay.
Build a reference calculation, not a promised sale price
fine-platinum weight = net platinum-bearing weight × purity fraction reference metal value = fine-platinum troy ounces × documented price per troy ounceUse only a quote whose meaning you can name: its source, currency, quote type, unit and time. A benchmark, exchange-related reference, dealer bid, dealer ask and refinery settlement are not interchangeable. See price-source guidance and how platinum quotes are described before entering a number.
A theoretical 100% payout is a math baseline, not a normal buyer offer. Testing, recovery, administration, shipping, payment timing, resale risk and margin can all affect a real transaction. For jewelry, a net metal calculation also excludes any separate value of stones, design or provenance.
Ask how purity and weight will be tested
Marks and visual inspection are screening evidence. A buyer may use instrument readings, physical measurements or laboratory assay depending on the item and lot. Each method has limits: surface readings may not describe every layer or component, and a precise test on an unrepresentative sample can still misstate a mixed lot.
- Ask which method supports the proposed fineness and whether it is non-destructive.
- Ask whether stones, clasps, mechanisms or attached base-metal parts are removed, returned, separately valued or excluded.
- For mixed material, ask how samples are selected and how the buyer handles a result you dispute.
- Do not send an item until you understand whether you can decline, how it is returned and who carries shipping and insurance risk.
Make every buyer show the same transaction
A buyer can quote a strong percentage while using a lower assessed fineness, a different reference time, a different price side, excluded weight or additional fees. Ask for the inputs in writing. If they cannot be supplied, the offer cannot be cleanly compared with another offer.
- What net platinum-bearing weight and unit did you use?
- What purity did you assign, and which test supports it?
- Which reference price, quote type, currency and timestamp apply?
- Is price fixed at acceptance, receipt, test, assay or a later settlement point?
- Which percentage and fixed deductions reduce proceeds?
- Are stones, packaging, product premiums or non-platinum components handled separately?
- What happens if I reject the final offer, and who pays to return the item?
Avoid these platinum-selling mistakes
- Treating every white-colored item as platinum without a defensible identification.
- Applying a purity percentage to a gross jewelry weight that includes stones or mechanisms.
- Using a static or retail-facing quote as if it were a buyer's binding bid.
- Assuming 100% payout is a realistic settlement rather than a theoretical baseline.
- Destroying an identifiable coin, signed piece or wearable jewel before checking non-melt value.
- Comparing advertised percentages without the tested weight, price time, deductions and payment terms behind them.
