What Is Stanley No. 4 Smoothing Plane Worth?

The typical price range for Stanley No. 4 Smoothing Plane is $75 - $125 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the cast iron body, specifically looking for hairline cracks or 'mouth' chips that significantly lower value.
• Completeness and originality of parts, including the iron, chip breaker, and rosewood components.
• The specific 'Type' or production era, with earlier types often commanding higher prices from collectors.
• Presence of original japanning (black enamel coating) on the bed, with higher percentages of intact finish increasing value.

How to Identify Stanley No. 4 Smoothing Plane?

• Check for the 'No. 4' casting behind the front knob and 'Stanley' or 'Bailey' markings on the bed.
• Verify the presence of authentic rosewood (Dalbergia) for the tote and knob, typical of pre-WWII models.
• Examine the lateral adjustment lever and the brass depth adjustment nut for period-correct Stanley branding.
• Look for specific 'Type' characteristics, such as the 'V' logo on the iron or the presence of a kidney-shaped lever cap hole.
