What to document first
For antique light bulbs, document the filament, glass shape, base type, maker marks, patent dates, packaging, voltage markings, and condition. Small differences can separate common bulbs from specialist collectibles.
Do not test old bulbs casually. Fragile glass, early filaments, and unknown electrical condition make display safety and preservation part of the appraisal conversation.
Value factors
Value depends on identification evidence, condition, completeness, market demand, intended use, and whether the assignment requires a written report or initial screening.
No public market evidence are asserted here. Use verified sold records, specialist databases, and object-specific evidence before relying on any market range.
When to request an appraisal
Request a professional appraisal when the item may be insured, donated, sold, inherited, divided in an estate, or reported for tax purposes. Include photos and documentation so the appraiser can recommend the right level of review.
