Stanley No. 1 Smooth Plane Value Guide

The Stanley No. 1 is the smallest bench plane ever produced by the Stanley Rule & Level Co., measuring just 5.5 inches in length. Its rarity stems from its niche practicality in 1869, leading to low production numbers that have made it a 'holy grail' for antique tool enthusiasts.

What affects the value of Stanley No. 1 Smooth Plane?

• Condition of the cast iron body, specifically looking for hairline cracks or 'mouth' chips that significantly lower value.
• Presence of original parts versus 'parts planes' assembled from mismatched eras or reproductions.
• The specific production 'type' or era, with earlier models often commanding higher prices near the $1,100 range.
• The preservation of the original japanning finish on the interior of the cast iron bed.

How to Identify Stanley No. 1 Smooth Plane?

• Verify the diminutive 5.5-inch length and 1.25-inch cutter width unique to the No. 1 model.
• Check for the original rosewood tote and knob, which should show age-appropriate patina without modern lacquer.
• Look for the 'Stanley' or 'L. Bailey's Patent' stamps on the lateral adjustment lever or the iron, depending on the production era.
• Examine the brass adjustment nut for the correct small-scale threading specific to this model.

History of Stanley No. 1 Smooth Plane

The Stanley No. 1 is the smallest of the bench planes produced by Stanley Rule & Level Co. Production began in 1869 and ended in the early 1940s. Due to its small size, it was often impractical for heavy carpentry and was sold in much lower quantities than its larger counterparts, making it one of the most sought-after prizes for tool collectors today.
