Bausch & Lomb Pocket Magnifier Value Guide

This Bausch & Lomb pocket magnifier represents the height of early 20th-century American optical craftsmanship from Rochester, New York. Highly collectible for its durable nickel-plated brass swing-out design, it was once a staple tool for professional jewelers and naturalists.

What Is Bausch & Lomb Pocket Magnifier Worth?

The typical price range for Bausch & Lomb Pocket Magnifier is $45 - $50 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the nickel plating, with higher value for pieces lacking significant brassing or pitting.
• Clarity of the glass lens, as scratches or chips significantly reduce the $45-$50 market price.
• Smoothness of the swing-out hinge mechanism and the tightness of the rivet.
• Presence of original patina versus over-polishing which can detract from the 1910-1940 era authenticity.

How to Identify Bausch & Lomb Pocket Magnifier?

• Look for the 'Bausch & Lomb' brand name stamped directly into the nickel-plated brass frame.
• Verify the swing-out mechanism is constructed from nickel-plated brass rather than modern polished steel.
• Check for the characteristic circular glass lens which should be free of modern plastic coatings.
• Confirm the folding design allows the lens to tuck completely into the protective metal housing.
