How do appraisers determine the value of antique artwork?
By the sales comparison approach: identifying the appropriate marketplace first, then reconciling realized prices for comparable works from auction records, dealer and gallery sales, and specialist databases such as Sotheby’s, Christie’s, Invaluable, and MutualArt. Our appraisers adjust each comparable for artist, size, medium, condition, and sale timing. Cost and income approaches apply only in narrow situations, such as reproducible works or income-producing art.
What documentation can raise the value of antique artwork?
Provenance records: original invoices, gallery labels, auction catalog entries, exhibition history, literature references, and catalogue raisonné listings. These materials confirm authenticity and market acceptance, which can justify selecting higher-priced comparables. High-resolution front and back photographs, plus notes on damage, restoration, and framing, also let the appraisal explain condition adjustments rather than just state a number.
Can one piece of antique art have more than one correct value?
Yes. Fair market value is the standard for most tax, estate, and equitable-distribution assignments, while retail replacement value, used for insurance scheduling, is typically higher because it assumes replacement through an appropriate retail market. Marketable cash value subtracts selling costs such as commissions and shipping. Using an insurance figure where fair market value is required can materially overstate the result, so the report must define its value standard explicitly.
What are the IRS requirements for donating antique artwork?
Form 8283 is required when the claimed deduction for noncash property exceeds $500, a qualified appraisal is required for most art donations valued over $5,000, and single items or groups of similar items over $20,000 require an attached appraisal summary. The rules are detailed in IRS Publication 561, Determining the Value of Donated Property.
