Examination & Inspection
Examination is the point at which an authentication claim meets the physical object. Materials, construction, production traces, dimensions, marks, wear and assembly must be observed before they are interpreted. The purpose is not to hunt for one dramatic sign, but to determine whether the object forms a coherent material history.
Strong inspection separates observation from conclusion. A modern-looking fastener, an unusual measurement or a fresh mark may be important, but each must be tested against legitimate variation, repair, replacement, storage, manufacture and later use. The defensible result explains what was seen, where it sits in the object's sequence and which claims it supports, challenges or leaves unresolved.

6 detailed topics
Establish how the object was made
Identify the materials, structure and manufacturing processes that must be physically plausible for the claimed object, date and origin.
Measure and identify the object
Turn visual impressions into reproducible physical observations and test marks or inscriptions within their material and chronological context.
Test age, change and association
Decide whether wear, surface development, repairs and present assembly form a coherent history or reveal later intervention and mixed components.
WORKED EXAMPLE
The convincing label on the wrong assembly
A boxed collectible carries a period-correct maker label, the expected colors and an apparently convincing aged surface. Closer inspection shows that the box dimensions fall outside the known format, the internal fasteners were installed through already-aged material and the label bridges a repaired seam rather than belonging beneath the original finishing sequence.
None of those observations should be judged alone. Together they indicate that genuine or period-compatible evidence may have been combined with later repair or assembly. The correct conclusion may be that the label itself is old, while the present package does not preserve the claimed original relationship.
Read the object as a sequence of physical events
Define the claim before inspecting
Document the object as received
Establish the expected manufacture
Map evidence to exact locations
Reconstruct the physical chronology
State a bounded conclusion
The strongest inspection findings are relational
Coherent evidence
Materials, production traces, dimensions, marks, wear and assembly reinforce one another when they occupy the expected locations and follow a plausible chronology.
Confidence rises when independent observations converge and legitimate variation has been considered rather than excluded by assumption.
Incoherent evidence
Suspicion increases when apparently old surfaces sit over fresh intervention, marks do not belong to the underlying material, dimensions conflict with the claimed format or genuine components lack an original association.
The result may be repair, composite assembly, later enhancement or false manufacture. Inspection should identify the conflict before assigning the final explanation.
COLLECTOR BOUNDARY
Do not create new evidence by damaging the object
Cutting, scraping, polishing, forcing joints, removing labels or dismantling unfamiliar mechanisms may destroy original surfaces and the sequence that inspection is trying to understand. A hidden area is not automatically more informative than an intact relationship.
Begin with non-destructive observation, controlled lighting, magnification, measurement and imaging. Escalate to specialist examination or scientific testing when the claim justifies the cost and the method can answer a defined question without disproportionate harm.
Detailed examination and inspection topics
Use the full guides below to examine how the object was made, record its physical characteristics, interpret marks and ageing, and identify later repair, alteration or mixed assembly.
Materials & Construction
Assess material types, layer structures, joints, fasteners, finishes and assembly sequences against the claimed period, maker and issue.
Tooling, Manufacture & Production Evidence
Read moulding, casting, machining, printing, fastening, decorating and tool-state evidence as traces of production rather than isolated clues.
Measurements & Physical Properties
Record dimensions, mass, thickness, proportions, density, balance and other physical properties using suitable methods and tolerances.
Marks, Labels & Signatures
Examine what a mark claims, how it was applied, whether it belongs to the object and how much evidential weight it can safely carry.
Wear, Patina & Age Indicators
Distinguish natural use and ageing from artificial distressing, transferred surface evidence, contamination, cleaning and later alteration.
Repairs, Alterations & Assembly
Identify repair, replacement, reconstruction, modification and composite assembly, then judge whether the intervention affects condition, originality or identity.
