Example scenario · illustrative, not a real seller
The logo, box and seller’s story all look convincing. Which evidence establishes the actual item is genuine—and which details merely look familiar?
What you’ll get
- An authenticity stop that comes before price research
- A labelled worked example, a visual process and an editable batch-time scratchpad.
- A device-only action checklist and one next move: Identify the evidence you are relying on
A disclaimer is not authentication.
A persuasive story and a familiar logo can make price research feel urgent. Authenticity comes first. An expensive comparison is irrelevant if the actual item cannot responsibly be offered as genuine.
Separate a clue from a conclusion
A serial-like number, packaging, receipt image or polished finish can be a clue to investigate. None is automatically conclusive. Documents can refer to a different item, and appearance alone can be insufficient for a category you do not understand.
Record what the evidence actually supports: source of acquisition, exact model, consistency of markings and relevant documentation. Keep private owner or transaction information out of public photos. Do not turn uncertainty into certainty merely because a seller sounds confident.
Read the platform rule before writing a disclaimer
eBay’s official intellectual-property guidance says sellers are responsible for authentic goods and describes counterfeits and unauthorized copies as not allowed. It advises not listing when unsure. “Buyer decides,” “inspired by” or a hidden logo is not a substitute for complying with the actual rule.
The same guidance says photos, videos and descriptions should be original or used with permission. Photograph the actual item and write what you can establish. Do not copy a convincing listing to borrow someone else’s evidence.
Decide what expertise is needed
Specialist goods can require specialist knowledge. Investigate the scope and limitations of any authentication service before paying. A platform handling a payment, accepting a listing or reviewing a complaint is not a universal authenticity certificate.
If a service cannot reach a conclusion, retain that uncertainty. Do not advertise an unsuccessful examination as authentication or suggest an agency has endorsed the item. This site cannot identify or authenticate goods from an amount entered in a calculator.
Price uncertainty as a reason to stop
The sourcing checklist is deliberately not a score. A marked box is your own reminder, not external approval. When authenticity or lawful ownership is unresolved, a larger potential margin does not compensate for the missing evidence.
A hypothetical ten-item review taking 12 chosen minutes per item requires 120 minutes before other work. That is a capacity exercise, not enough time to authenticate ten items. If responsible research takes longer, reduce the batch or pass; never force a conclusion to meet a timer.
Keep safety as a separate gate
Even a genuine item can be recalled, damaged, incomplete or restricted. Check relevant recalls and product requirements after establishing identity. Authenticity is not the same as safe condition or permission to ship.
Finish with a clear decision: adequate basis to continue the remaining checks, more evidence needed with the item not listed, or pass. A persuasive story should not be the strongest entry in your evidence record. If it is, stop before treating a hoped-for resale price as money you can rely on.
Worked example · hypothetical, not a real seller
An authenticity stop that comes before price research
A deliberately chosen planning example for this decision. It is not a real transaction, a product appraisal, an observed market result or permission to sell. Replace the inputs only after the relevant checks.
12 chosen minutes per item × 10 items = 120 minutes (2 hours). Against 90 available minutes, that leaves a 30-minute capacity gap. These are planning assumptions, not measured productivity or enough time to establish safety or authenticity. Take the time the actual task needs, reduce the batch or pass.
| Measure | Example value |
|---|---|
| Planned work (minutes) | 120 |
| Available time (minutes) | 90 |

Batch-time scratchpad

Can I say “not sure if genuine” and let the buyer decide?
Not as a workaround for eBay’s authenticity rule. Its official guidance says sellers are responsible for genuine items and should not list when unsure. A disclaimer or altered photo does not establish authenticity or make a prohibited item permitted.
Do this next · one concrete move
Identify the evidence you are relying on
Read the platform’s current authenticity and intellectual-property rules, and use appropriate expertise. Never turn an uncertain result or a paid service receipt into a claim that the item was authenticated.
