What affects the value of Cast Iron Frog Doorstop?

• Presence of original cold-painted finishes can significantly increase the value toward the $95 range.
• Identification of a specific foundry mark, such as Hubley, adds a premium for serious collectors.
• The overall condition of the iron, specifically the lack of deep rust or structural cracks, maintains the $85-$95 valuation.
• The level of casting detail, particularly in the frog's skin texture and facial features, influences desirability.

How to Identify Cast Iron Frog Doorstop?

• Check for a heavy, solid cast iron weight consistent with early 20th-century American manufacturing.
• Look for a seam line along the sides, indicating a two-part sand casting process typical of the 1900-1940 era.
• Examine the underside for potential maker marks from foundries like Hubley or Wilton, though many remain unbranded.
• Observe the surface texture for natural pitting and aged patina that distinguishes antique iron from modern reproductions.
