Antique appraisal guide: how professional valuations work
Understand the different types of appraisals, when you need one, and how to get the most accurate valuation for your antiques.
The three main types of antique appraisal
Not all appraisals serve the same purpose, and the type of appraisal determines the value figure it produces. Insurance replacement appraisals establish the cost to replace an item with a comparable one at retail — these produce the highest value figures because they reflect what you would have to pay to replace the piece tomorrow. Fair market value appraisals reflect what a willing buyer would pay a willing seller when neither is under pressure — the standard used for estate settlement, charitable donation tax deductions, and equitable distribution. Liquidation value appraisals reflect what an item would bring in a forced or quick sale — the lowest figure, used in bankruptcy proceedings or forced estate liquidations. Using the wrong type of appraisal for a purpose creates problems: an insurance replacement value figure used for donation purposes would overstate the tax deduction, which is illegal.
What a qualified appraiser actually does
A qualified appraiser physically examines the object, researches its authenticity and attribution, identifies comparable sales in auction records and dealer inventories, and produces a written report documenting their methodology. The examination phase involves checking construction details, marks, condition, and any prior restoration. Research uses auction house databases, price guides, specialist literature, and sometimes consultation with subject-matter experts. The written appraisal includes a description of the object, the appraiser's credentials, the methodology used, comparable sales cited, the effective date of the appraisal, and the value conclusion. A credible appraisal for IRS purposes must be conducted by a qualified appraiser as defined by IRS regulations — someone with verifiable education and experience in the relevant specialty, who is not the donor or a party with a financial interest in the transaction.
Getting the most from auction house and dealer valuations
Major auction houses offer free walk-in valuation days and online submission services for potential consignments. These are useful as a preliminary assessment, but remember that auction house specialists have a vested interest in accepting desirable consignments — estimates may be optimistic to attract business. Estimates given by dealers are similarly colored by whether the dealer is buying or selling. For a sale, a dealer's offer reflects their need to make a profit on resale, typically 40–100% markup from purchase to sell price, so their buying price will be significantly below true market value. For buying from a dealer, their asking price reflects that markup. Understanding these structural factors helps you interpret valuations you receive. AntiqLens provides an independent market reference point to help you calibrate what you're hearing from buyers and sellers with their own interests in the transaction.
FAQ
How much does a professional antique appraisal cost?
Appraisal fees typically range from $150–$400 per hour for a qualified independent appraiser, with a minimum fee for even simple single-item appraisals. Written appraisals for insurance or estate purposes covering multiple items may cost $500–$2,000 or more depending on the number of items and research required. Appraisers should never charge a percentage of the appraised value — percentage-based fees create a conflict of interest and are prohibited by professional standards. Get a fee estimate in writing before engaging an appraiser.
Can I use AntiqLens for insurance documentation?
AntiqLens provides market reference price ranges that are useful as a preliminary valuation guide and for making insurance coverage decisions — for example, deciding whether an item is valuable enough to warrant scheduling as a separate item on a home insurance policy rather than relying on blanket contents coverage. For formal insurance claims, most insurers require a written appraisal from a qualified human appraiser with credentials. AntiqLens references can help you decide whether a formal appraisal investment is warranted before committing to that process.
What is the difference between an appraiser and an auction house specialist?
A qualified independent appraiser has no financial stake in the outcome of your appraisal and produces a value opinion solely based on their professional analysis and research. Auction house specialists are experts in their categories who work for the auction house — they have deep knowledge but their primary job is to identify consignments worth selling through their house. Their estimates serve dual purposes: providing guidance to potential consignors and identifying property for the auction house's business. Both are valuable, but independent appraisers provide the objective documentation needed for legal, tax, and insurance purposes, while auction house specialists provide the best guidance on current market saleability and realized price expectations.
