Dealer / quick-sale range
A lower planning range for situations where speed and dealer margin matter more than maximizing the final sale price.
Antique value research
Build a quick planning range from the item type, age, condition, maker, materials, provenance and current buyer demand. Add a recent genuinely comparable sold result when you have one.
What’s It Worth?
Get a quick resale-value range from the item type, age, condition, maker, materials, provenance and current demand. Add a recent comparable sold price when you have one for a tighter estimate.
Estimated current resale value
Midpoint estimate: $350
This is a screening estimate, not a certified appraisal. Authenticity, rarity, regional demand and hands-on inspection can materially change value.
Read the result
The calculator separates selling speed and channel instead of presenting one false-precision figure.
A lower planning range for situations where speed and dealer margin matter more than maximizing the final sale price.
The central planning range produced from the evidence you enter. This is the number to refine with close sold comparables.
A higher asking context that may require more time, presentation, buyer reach and selling costs. Asking price is not the same as sold value.
Build an evidence file
The strongest improvements to an estimate usually come from better identification and better market evidence, not from adding more descriptive adjectives.
Value drivers
Different categories weigh these signals differently, but the same six questions are a useful screening framework.
| Factor | Stronger evidence | What can weaken confidence |
|---|---|---|
| Maker / attribution | Readable mark, documented maker, model or catalogue match | Unverified attribution based only on appearance |
| Age / period | Construction, marks and documentation agree | Revival or reproduction confused with an earlier period |
| Condition | Complete object with documented, appropriate conservation | Structural damage, missing parts or heavy alteration |
| Originality | Original components appropriate to the category | Replacement parts or refinishing that changes collector appeal |
| Provenance | Traceable records relevant to authenticity or history | Stories that cannot be documented |
| Sold comparables | Recent sales of genuinely similar examples | Active asking prices or unrelated record-setting sales |
Estimator limits
Move beyond a quick estimator when authenticity, material, rarity or formal documentation could materially affect the decision.
Local dealer research
Location can influence where and how an item is sold, but it does not create a universal state price. Use local store directories to identify dealers and selling options; use comparable sold items to research the object itself.
