01Use the official source
Enter the certification or report number only on the issuing organization's official website. Search advertisements and screenshots are not authoritative.
- Type the official domain directly
- Confirm issuer, number and status
- Treat unavailable or mismatched records as a stop signal
02Match every detail
Date, denomination, variety, grade, measurements, weight and comments should agree with the physical object.
- Compare label text character by character
- Match photographs when available
- Investigate any discrepancy before proceeding
03Inspect security and integrity
Holder construction, seams, holograms, fonts, labels and tamper evidence can reveal substitution or counterfeit packaging.
- Study current issuer security features
- Check for opening or resealing
- Do not rely on a copied certification number
04Document chain of custody
Invoices, prior listings, high-resolution photographs and ownership records strengthen provenance and help resolve later questions.
- Save original purchase documentation
- Photograph identifying marks
- Record transfers, services and repairs
