Collector checklist: verify, handle, and document
Use this checklist to prepare before buying, valuing, or storing a collectible. It summarizes practices from named public institutions in original language for CBG COIN readers. It cannot authenticate, grade, or value a specific coin or note.
What should I record before I buy a collectible?
Save the listing URL, seller name, price, date, all available photos, certificate number, and any stated condition before you pay. For a graded item, record the full label description and the certification number together. This gives you a fixed comparison record if a question later arises; it does not make a photograph or listing description proof of authenticity.
How do I check a PCGS or NGC holder without overclaiming what the result means?
Use the grading company’s official lookup, then compare the returned description, grade, and available images with the actual holder and item photographs. A matching result is a useful check, but it does not replace inspection of the item in hand, its surfaces, or a review of any change after certification. Stop and ask for clarification when the label, image, or database result does not match.
What can listing photos tell me, and what can they not tell me?
Photos can show the offered item, the label, obvious marks, and whether the pictured object appears to match the listing. They cannot reliably settle authenticity, hidden damage, altered surfaces, weight, dimensions, or details outside the frame. For a significant purchase, ask for clear front, back, edge or holder photographs and compare them with the description and any official certificate record.
How should I handle and store coins and paper money?
Handle coins as little as possible and support them by the edge rather than the design surfaces. Do not clean a coin simply to improve its appearance. Store coins only in materials intended for numismatics, away from damaging contamination. Paper money has different risks: moisture, heat, pollutants, adhesive materials, folds, and repair attempts can all cause harm. Keep notes stable and dry, and do not wash, iron, tape, or flatten them at home.
What should I do first with an inherited collection?
Keep the collection together until you have made a basic record. Photograph boxes, envelopes, holders, handwritten notes, purchase receipts, and the items as found. Do not clean, separate, or discard material merely because it looks ordinary. A record of how items were kept can help later research, appraisal, insurance, or family decisions. Make decisions item by item after the record is complete.
Can a quick visual check authenticate a Hong Kong banknote?
No. A quick visual check is only a screening step. For a specific modern issue, consult the official information for that series and compare the printed design and stated security features carefully. Historical notes, varieties, and older issuer issues require issue-specific references and often professional examination. Do not declare a note genuine or counterfeit from one image, a single feature, or an online listing alone.
Where should I go next?
Read the Collector Q&A for buying and valuation questions, or browse the collector guides for source-backed articles. For a specific item, send clear photos and all known documentation through the contact page; an inquiry is not a guarantee of authentication or value.
