Authentication and Valuations & Appraisals:

HKPNC is delighted to provide the authentication service. Through in-house specialists and consultation with external experts, we can offer an accurate opinion on the authenticity of items submitted to us. Please note that we do not currently offer certification.


We also provide professional valuations and appraisals services for full collections as well as single items, mo matter whether you are looking to sell or are simply looking to establish current market prices. For large private collections or institutional collections, as well as for individuals requiring valuations and appraisals for probate or insurance purposes, we can provide a formal, written report including the condition of the items, historical transaction prices and information on recent sales of comparable items.


Confidential verbal valuations and appraisals are generally free but we do charge a modest fee for the written report, based upon our time involved and level of details required for the report. However for valuations and appraisals requiring significant time or travel expenses, we reserve the right to seek reimbursement of reasonable out-of-pocket expenses. In the event that any transaction is completed with us, any such expenses will be waived or reimbursed in full.


You are always welcome to bring items to our office for evaluation during which authenticity and value of single items or small collections can often be estimated immediately. Alternatively if you are unable to visit our office in person, please send us clear images of the items in question. While it is often possible to authenticate and evaluate the items by images alone, naturally first hand inspection is the best way for an accurate initial authentication, valuation and appraisal.
