How to find out what an antique is worth
To research what an antique is worth, identify it as closely as possible and compare completed sales of similar objects. Record maker, materials, size, condition, sale date and currency. Use a range that reflects the differences and gaps in the evidence.
Why are asking prices different from sold prices?
An asking price is the amount a seller requests. A completed sale records a transaction, subject to the platform’s reporting rules. A high listing price does not show that buyers paid that amount. Check whether an auction result includes fees before using it as a comparison.
What makes a useful comparable sale?
Look for similarities in maker, model or type, materials, dimensions and condition. Document meaningful differences rather than averaging unrelated objects. A repaired example and an intact example may not be interchangeable comparisons.
How should I record a value range?
Keep the original currency, sale date, venue and source link with every comparison. State which costs are included. Record the reason for the low and high ends of your range, and identify unresolved questions such as maker, material or repair history.
When is professional appraisal useful?
If you need a valuation for a formal purpose, first ask the receiving organization which qualifications and report format it requires. For a purchase or sale, seek specialist help when authenticity or material questions could materially change your decision. A photo-based estimate is a preliminary research aid.
