Before you start

Frequently Asked Questions

How do you value my 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 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 actually do with it?

Track your collection's value over time, export a report for your wealth manager or insurer, borrow against a piece, insure it on a current valuation, or take an introduction to a buyer when you choose.

How current is the data?

It updates as new auction results land, across 100+ houses, so your collection is re-valued on the latest real sales rather than a once-a-year estimate.
