What appraisers actually look for when they examine an object
Appraisers don't guess — they work through a consistent checklist: what is it made of, who made it, what condition is it in, how rare is it, and is there paperwork backing its history. Current market demand then determines what all of that adds up to today. You can run the same checklist on almost anything in an estate before deciding what deserves closer research.
Start with condition, not sentiment
Condition is usually the first thing an appraiser checks, because damage, repairs, and wear limit value no matter how good the piece otherwise is. That means looking for cracks, chips, replaced parts, refinishing, water damage, fading, and any repairs that weren't done by a professional conservator. A repaired chair leg or a repainted surface isn't automatically worthless, but it changes the conversation. Appraisers separate honest age-related wear from later alteration early, because those are treated very differently.
Identify the maker or mark
A maker's mark, stamp, label, or signature narrows down who made an object and roughly when. Appraisers check marks against reference sources rather than trusting them at face value, since marks get copied, altered, or misapplied over the years. The mark's location, wear pattern, and consistency with the piece's construction all matter — a crisp, new-looking stamp on an otherwise aged object is a flag worth investigating, not a mark to accept at face value.
Materials and construction reveal the real story
What something is actually made of — solid wood versus veneer, sterling versus plate, hand-cut versus machine-cut joinery — tells an appraiser more than the object's surface appearance. Construction methods changed over decades in fairly predictable ways, so hardware, saw marks, glue types, and casting seams can date a piece even without any mark at all. This is why appraisers turn things over, check undersides, and look closely at joints before forming an opinion.
Rarity, provenance, and current demand
An object can be old, well-made, and still common — mass production means plenty of period pieces exist and aren't rare. Paperwork, receipts, letters, or a documented chain of ownership can support a higher value when they exist, but appraisers still weigh that against what buyers are actually paying for that category right now. Taste shifts over time: categories that were in high demand a generation ago can be soft today, and that current market reality matters as much as history does.
Questions
What's the single most important factor in an appraisal?
- There isn't one — appraisers weigh condition, maker, materials, rarity, and current demand together. A strong result in one area doesn't override a weak one elsewhere.
Does having the original box or paperwork help?
- It can support authenticity and completeness, which buyers value, but paperwork alone doesn't set a price. It's one more data point in the full picture.
Can I do this kind of assessment myself before selling?
- You can run through the same framework informally, but a formal opinion of value, especially for insurance, tax, or estate purposes, should come from a certified appraiser.
