Helen Hall, AAA Certified Memorabilia Appraiser

The path to specialism

Helen Hall began as an antiques dealer at sixteen. An internship at Christie's followed, where she spent hours matching James Bond film props against original production records. That work established what would become her signature methodology: provenance verified by deep research, meticulous analysis and independent documentation.

She rose to Vice President and Head of Entertainment Memorabilia at Christie's, working across the New York and London salerooms on the most significant single-owner sales in the category. In addition, Helen has a broad experience across fine art, decorative arts, and collectibles — a cross-category fluency that matters when an estate contains material spanning several specialist departments.

In 2008 she founded DIG Appraisals.

Insurance

High-value private collections

Periodic reappraisal for collectors whose pre-2020 acquisitions are now insured at fractions of current fair-market value. Cobain, Hendrix and Beatles material in particular has appreciated faster than typical insurance review cycles.

The DIG method

Every DIG appraisal is grounded in three things: verified comparables drawn from the major and secondary auction record, independent provenance checks against photographic and documentary evidence, and a written report that satisfies the highest applicable standard: IRS, AAA, USPAP. We do not rely on single-source COAs, dealer letters, or uncorroborated authentication services.

For high-value items, the DIG IQ scoring framework adds a documented breakdown across provenance, verification, market liquidity, and historical delta, giving the appraisal a defensible numerical scaffold under cross-examination.
