Antique lamps range from humble oil lamps to famous leaded glass designs. The style of the lamp, the quality of the shade and the base markings determine value.
Types of antique lamps
- Oil and kerosene lamps: glass, brass and decorated bases with glass chimneys
- Leaded glass lamps: shades made from many pieces of colored glass joined with metal
- Reverse-painted lamps: shades painted on the inside
- Art Nouveau and Art Deco lamps: figural bronze or spelter bases, glass shades
- Banquet and parlor lamps: tall, ornate Victorian lamps
Leaded glass lamps and reproductions
The most famous leaded glass lamps can be extremely valuable — which is why "Tiffany-style" lamps are everywhere. Most are modern reproductions. Signs of genuine quality include:
- Fine, varied, high-quality glass with depth and texture
- Careful, even leading
- Signed shades and bases (signatures are also faked)
- Proper patina on bronze bases
Anything claimed as a major maker should be authenticated by a specialist.
Check the base and burner
Oil lamp burners often carry maker names and patent dates. Bases may be marked on the underside.
Condition
- Cracked or replaced glass panels
- Damaged chimneys and shades
- Corrosion on metal parts
- Wiring condition on electric lamps
Rewiring
Old wiring can be a fire hazard. Rewiring with sympathetic, safe components is accepted by most buyers and doesn't usually hurt value much. Keep original parts if replaced.

Frequently asked questions
How do I know if my lamp is genuine leaded glass by a famous maker?
Check glass quality, leading, signatures and patina, but get a specialist's opinion — reproductions are very common.
Are old oil lamps worth money?
Most are modest; decorated, rare or early lamps can be worth more.
Does rewiring lower an antique lamp's value?
Usually not much, and it's safer. Keep the original parts.
