What Is Stanley Folding Rule Worth?

The typical price range for Stanley Folding Rule is $75 - $120 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Verify the material is genuine boxwood, characterized by a tight grain and a deep yellow-to-amber patina.
• Check for authentic brass fittings and hinges that are flush with the wood and secured with small pins.
• Confirm the 24-inch total length when fully extended, featuring graduated markings typical of the 1890-1920 era.
