While we take great pride in our company history here at The STANLEY Works, we do not participate in a secondary market for our products as it would not be appropriate for us to speculate the value. STANLEY also does not officially endorse any single company or person to assess the value of these products.
We do understand your interest in STANLEY and can direct you to some unofficial resources that might help with your search.
Here are some places to start:
Antique & Collectible Stanley Tools : Guide to Identity & Value by John Walter
The Internet also has many good resources on antique STANLEY Tools as well.
Again, we thank you for your interest.
