Banker's Lamp Value Guide

The Banker's Lamp, famously known as the Emeralite, is a 1909 Harrison D. McFaddin patent that became a staple of American financial and academic institutions.

What Is Banker's Lamp Worth?

The typical price range for Banker's Lamp is $150 - $250 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the glass shade, as chips or cracks in the green cased-glass significantly reduce the $150-$250 market value.
• Originality of the brass patina, with unpolished, aged finishes typically commanding higher prices from collectors.
• Presence of original manufacturer labels or patent markings from H.D. McFaddin & Co.
• Functional integrity of the internal wiring and the smoothness of the adjustable shade hardware.

How to Identify Banker's Lamp?

• Check for the 'Emeralite' brand name often stamped on the brass base or etched into the glass shade.
• Examine the shade for a 'cased' glass construction, featuring a green exterior layer and a white opal interior layer.
• Verify the heavy brass base and adjustable swivel mechanism characteristic of 1920-1940 United States production.
• Look for the original pull-chain switch which was standard for authentic early 20th-century models.

History of Banker's Lamp

The banker's lamp, also known as an Emeralite lamp, was first patented in 1909 by Harrison D. McFaddin in the United States. Its distinctive green glass shade and brass base became a staple in banks, libraries, and offices throughout the early to mid-20th century. The green glass was believed to be soothing to the eyes and help reduce eyestrain, especially during long hours of paperwork under incandescent lighting. These lamps are celebrated for their timeless aesthetic and functional design, enduring as a symbol of classic office decor.
