What Is Planet Jr. Wrench Worth?

How to Identify Planet Jr. Wrench?

• Look for the 'Planet Jr.' name embossed in raised capital letters directly into the cast iron handle or head.
• Verify the material is heavy, dark cast iron, which was the standard for S.L. Allen & Company tools during the early 20th century.
• Check for specific part numbers or unique cutout shapes designed to fit the proprietary nuts found on Planet Jr. seeders and cultivators.
• Examine the patina for authentic age-related wear consistent with 1900-1940 manufacturing, rather than modern smooth finishes.
