Expert Guide Library

Professional Knowledge. Accessible Expertise. Instant Downloads

The DJR Expert Guide Library documents the DJR Standard—professional methodologies used to evaluate authenticity, assess value, and protect long-term worth in markets often shaped by conflicting, incomplete, or commercially motivated information. The library includes both Expert Guides and Discovery & First-Stage Decision frameworks, each designed to support disciplined judgment at the appropriate stage of uncertainty.

Every guide distills over a decade of real-world appraisal and authentication experience into clear, precision-built frameworks highlighting critical methods, red flags, and identification cues—helping collectors, resellers, advisors, and estate handlers reduce risk, avoid common $500–$5,000+ mistakes, and make informed decisions before committing time, money, or formal services.
