From one dragon dollar to a specialist appraisal service
Gu Jin Jian Bao works with Hong Kong and Macau collectors who want a clear, private way to appraise and sell old coins, silver dollars, Renminbi banknotes, stamps, gold, porcelain and antiques.
We start with photos, explain the key factors that affect value, and only arrange an in-person appraisal when the item is suitable. Final quotes depend on authenticity, variety, condition, rarity and current market demand.
How we work
- Send clear photos of the front, back, edge, base mark, details and certificates where available.
- We review the item type, condition and market direction, then tell you whether it is worth a physical check.
- Suitable items can be viewed privately in Hong Kong or Macau, with settlement by cash or bank transfer after both sides confirm the price.
What to prepare before contacting us
- Clear photos in natural light, without cleaning or polishing the item first.
- Size, weight, quantity, source, certificates, boxes or old receipts if available.
- Separate groups for coins, banknotes, stamps, porcelain and gold so we can reply faster.
