What Is Porcelain Door Knob Worth?

The typical price range for Porcelain Door Knob is $20 - $30 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

  • 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.

History of Porcelain Door Knob
