Glass Door Knob Value Guide

Faceted glass door knobs are iconic fixtures of early 20th-century American architecture, prized for their ability to refract light and add a sparkling elegance to interiors. Originally mass-produced by manufacturers like Corbin and Yale, these machine-pressed collectibles represent a bridge between Victorian craftsmanship and Art Deco utility.

What Is Glass Door Knob Worth?

The typical price range for Glass Door Knob is $45 - $45 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Clarity of the glass, as antique pieces may develop a slight purple or straw tint due to manganese or selenium exposure.
• The presence of original mounting hardware and matching rosettes significantly increases the $45 market value.
• Condition of the facets, specifically looking for sharp edges without significant chips or 'flea bites'.
• Rarity of the specific mold design, with intricate patterns from companies like Corbin fetching higher premiums.

How to Identify Glass Door Knob?

• Look for the distinct faceted geometric patterns characteristic of the 1900-1940 era.
• Check for a heavy, machine-pressed glass construction rather than modern lightweight plastic imitations.
• Examine the center for a silvered or mirrored backing which was often used to enhance the glass's brilliance.
• Verify the presence of a metal shank, typically made of brass or iron, designed to fit standard vintage spindles.

History of Glass Door Knob

Glass door knobs became popular in the United States during the Victorian era and remained a stylish choice through the Art Deco and Mid-Century Modern periods. They were often machine-pressed from molten glass into decorative molds, offering an affordable yet elegant alternative to more expensive metal or ceramic knobs. The distinct faceted designs caught and refracted light, adding a touch of sparkle to interiors. Many were mass-produced by companies like Corbin and Yale, becoming a staple in American architecture for decades.
