DJR Expert Guide Series, Vol. 838 — Real vs Fake: How Appraisers Identify Altered Items
Altered items are among the most difficult pieces to evaluate because they sit in a gray area between authentic and counterfeit. While a genuine base object may be present, changes such as repainted surfaces, added signatures, replaced components, or staged aging can dramatically distort authenticity and perceived value. Many collectors assume an item is original simply because major features appear correct, yet subtle inconsistencies in surface texture, wear patterns, markings, or construction frequently expose later modification. Without a structured appraisal framework, it becomes easy to trust appearance over evidence or overlook contradictions that a trained eye would see immediately. Understanding how professionals detect alterations is essential for avoiding misrepresentation, overvaluation, or purchasing items whose authenticity has been compromised.
DJR Expert Guide Series, Vol. 838 provides a complete, non-destructive, appraisal-grade workflow for identifying altered items using the same methods employed by professional authenticators. You’ll learn how to analyze surfaces, finishes, markings, replaced parts, structural components, artificial aging patterns, magnified inconsistencies, and comparative references to determine whether an item remains fully original—or has been modified after manufacture.
Inside this guide, you’ll learn how to:
Distinguish authentic items from those altered after production
Detect surface refinishing, repainting, varnish changes, and texture inconsistencies
Identify artificially aged materials and staged distressing
Recognize replaced components, mismatched wear, and construction contradictions
Evaluate altered signatures, labels, hallmarks, and edition markings
Detect structural modifications, reassembly, cutting, shaping, and adhesive repair
Use magnification and lighting to reveal hidden clues
Compare items against verified references for total-consistency analysis
Know when to escalate an item for lab testing or expert specialist review
Whether you're evaluating artwork, memorabilia, antiques, collectibles, or modern items susceptible to alteration, this guide gives you the professional structure needed to detect non-original modifications with confidence.
