What Is Octagonal Glass Door Knob Worth?

The typical price range for Octagonal Glass Door Knob is $25 - $40 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Market demand for authentic 1900-1930s period hardware for historic home renovations.

How to Identify Octagonal Glass Door Knob?

• Look for the distinct eight-sided octagonal geometry with sharp, light-reflecting facets.
• Check for original brass hardware components, which were standard for US manufacturing in this era.
• Examine the glass for a slight lavender or straw tint, often caused by manganese or selenium exposure over time.
• Verify the presence of a threaded spindle hole consistent with early 20th-century mortise locks.
