Appraisal & Valuation
A defensible basis of value you can stand behind
Every appraisal and every claim has to answer one question: where did the number come from, and does it hold up? Support your opinion of value with cleared auction results from across the whole market, not asking prices and not a single dealer's offer, each one traceable to its house, sale date, and lot.

Built for the way appraisers actually work
From insurance schedules to estate and litigation work, cleared cross-market comparables give every appraisal a defensible foundation. Here is where they fit, and the tools that get you there.
Defensible comparable sales
Support your opinion of value with recent cleared results for genuinely comparable pieces, drawn from the whole market rather than one channel.
- Cleared hammer prices, not asking prices or dealer offers
- Search by maker, model, material, date, and condition
- Every result traceable to house, sale date, and lot
Insurance & claims schedules
Set scheduled values and settle damage or loss claims on neutral market evidence that reflects what comparable items actually clear for.
- Current market comparables for scheduling and renewal
- Flag coverage that has drifted from market reality
- Exportable comparable reports for the claim file
Estate, gift & tax valuations
Document fair market value with third-party comparable sales that stand up to IRS and estate scrutiny, as of any date you need.
- Point-in-time results for date-of-death and gift work
- Source attribution for every comparable used
- Consistent USD pricing across 27 currencies
Litigation & dispute support
Bring objective, independent market evidence to disputes, divorces, and damage claims. A neutral basis of value carries weight precisely because no party controls it.
- Independent third-party market evidence
- Full provenance for exhibits and workfiles
- Coverage across every major collectible category
