Appraisal fees depend on the type and number of items being evaluated.

You’ll always receive an upfront estimate before any work begins.
A typical appraisal appointment takes about 30–60 minutes per item. More complex pieces — especially vintage watches or multi-item estates — may require additional research. We’ll provide an estimated timeline before your visit so you know exactly what to expect.
