Porcelain Door Knob Value Guide

These late 19th and early 20th-century porcelain door knobs emerged as a sanitary and cost-effective alternative to traditional metal hardware. Originally favored for service areas like kitchens and bathrooms, they are now highly sought after as charming, functional elements of period-correct home restoration.

What affects the value of Porcelain Door Knob?

• Condition of the porcelain glaze, specifically the absence of 'spider' cracks, chips, or deep staining.
• Presence of original mounting hardware, including the metal shank and set screws.
• Completeness of the set, as matching pairs for both sides of a door command higher prices than single knobs.
• The purity of the white color, with consistent firing and minimal manufacturing defects.

How to Identify Porcelain Door Knob?

• Look for a smooth, white glazed finish characteristic of late 19th-century American porcelain production.
• Check for a central metal spindle hole, often featuring a square profile typical of 1880-1920 hardware standards.
• Examine the shank for signs of aged iron or brass, which should show natural patina rather than modern plating.
• Verify the weight; authentic antique porcelain knobs have a dense, heavy feel compared to modern ceramic reproductions.
