DIG Appraisal

Insurance Coverage

After acquiring a significant piece through Propstore, your insurer will require a formal appraisal to underwrite the policy. A sale price is not an appraisal. It reflects what one buyer paid on one day. A USPAP-compliant appraisal establishes replacement value for ongoing coverage.

Estate Planning

If entertainment memorabilia acquired through Propstore forms part of a collection with estate value, a qualified appraisal is required for IRS Form 706. DIG has appraised collections for some of the most significant entertainment estates of the past two decades.

Charitable Donation

Donating a significant piece to a museum or institution? The IRS requires a USPAP-compliant appraisal completed within a specific window. See the Form 8283 guide for full requirements.

Consignment Due Diligence

Consignors working with Propstore who want an independent valuation before committing to a reserve — or who need documentation of value for their own records — can engage DIG for a pre-consignment appraisal.

About Propstore

Why the Independence Matters

An appraisal from the marketplace where you acquired a piece carries an inherent conflict of interest. The IRS does not accept it. Insurers are sceptical of it. A probate court will challenge it.

DIG Appraisals has no financial interest in Propstore transactions. Helen Hall's fees are fixed, based on the complexity of the appraisal — never a percentage of value and never contingent on the outcome of a sale. That is the structural independence that makes a DIG appraisal legally defensible.
