Before you start

Frequently Asked Questions

How do you value clients’ assets?

On real comparable auction sales. For each item we find the lots like it that actually sold, and show the low, median and high, with the trend over time. It is the hammer price, not an asking price or a dealer's offer.

Is the valuation really neutral?

Yes. We do not buy or sell your clients’ items and we take no cut of a sale, so we have no reason to shade the number. Any lending, insurance or buyer offer is clearly separate from the valuation.

What can I do with it for clients?

Track each client’s collection over time, export a valuation into their statements and reviews, support a lending or insurance decision, or take an introduction to a buyer when they choose.

How current is the data?

It updates as new auction results land, across 650+ houses, so each client’s collection is re-valued on the latest real sales rather than a once-a-year estimate.
