Each artist hub coordinates the three things collectors and executors come to DIG for: current market values, USPAP-compliant appraisals, and the market study.
$22.3M tracked across 28 verified lots, 2006-2026. DIG IQ 96 / 100. Median 8.4× over auction estimate. Only single-artist memorabilia market with documented repeat-sale appreciation (Mustang +52% in 4 years).
Verified Woodstock and Monterey provenance sets the market ceiling for entertainment memorabilia. USPAP appraisals for Stratocasters, stage-worn clothing, vintage performance photography, handwritten material, and personal effects.
USPAP appraisals for Beatles instruments, signed records, handwritten lyrics, Apple-era material, and individual member memorabilia (Lennon, McCartney, Harrison, Starr). Provenance scrutiny is at the highest tier given category value and historical forgery activity.
