What DIG Appraises

Every engagement is USPAP-compliant and delivered personally by Helen Hall, AAA Certified Member. Services group three ways: by the object you own, by the purpose you need it for, and through institutional partnerships.

Not sure which to start with?

Inherited a memorabilia collection? Start with Celebrity Estate Planning. Helen can scope the full engagement before you commit.

Donating to a museum? IRS Appraisals. The Form 8283 deadline is strict and the appraiser must be qualified.
