DJR Expert Guides document the DJR Standard—concise evaluation frameworks designed to assess authenticity, condition, and value risk before appraisal, grading, sale, or other irreversible decisions in markets where fakes, forgeries, and misidentified items are common. These guides replace guesswork with structured, defensible methods drawn from real-world appraisal and authentication practice, providing clarity and confidence when the stakes are high.

Expert Guides provide professional knowledge and methodology but do not provide appraisal, authentication, or expert opinions for specific items, collections, or estates. If you require an expert opinion, formal documentation, or item-specific review, please explore our Services & Pricing.

“One avoided mistake can save far more than the cost of the guide.”
