How do appraisers establish what a painting is worth?
Through sales comparison: recent arms-length auction and private-sale records for comparable works by the same artist, adjusted for size, date, subject, condition, and market timing. Appraisers normalize prices to include buyer's premium, prioritize verified sale prices over pre-sale estimates, and document venue, sale date, and lot number for each comparable. Professional price databases and dealer records supplement auction catalogs; informal asking prices are secondary context, not evidence.
What is the difference between fair market value and retail replacement value for a painting?
Fair market value is the price a willing buyer and seller would agree to, and it governs charitable donations and estate or gift tax work. Retail replacement value is the cost to replace the painting with one of like kind and quality in the retail market, and it is the typical basis for scheduled fine art insurance. The two can differ substantially, so a credible report states which definition it develops and why.
What do the IRS rules require when donating a painting?
A qualified appraisal and Form 8283, Section B, whenever the claimed deduction exceeds $5,000, with the appraisal dated no more than 60 days before the contribution. For artwork deductions of $20,000 or more, the IRS can request the complete appraisal and may refer it to its Art Advisory Panel for review. A gallery letter or auction estimate does not satisfy these substantiation rules.
Do restoration and condition problems change a painting's appraised value?
Yes, and often significantly. Appraisers examine craquelure, tears, overpaint, relining, and prior restorations, frequently using raking light or UV examination, then adjust comparable sale prices downward for defects the comparables did not share. Assuming a painting in fair condition will match pristine auction results leads to inflated expectations, and undisclosed restoration discovered later is a common reason values get revised.
Is an auction estimate the same as an appraisal?
No. An auction estimate is a nonbinding prediction of sale outcome, and a valuation letter is an approximate opinion; neither carries the documented methodology, comparables analysis, and certification of a formal appraisal report. For tax, insurance, or legal matters, only a report that states its intended use, value definition, and market evidence will withstand scrutiny from insurers, courts, or the IRS.
