Cast Iron Cannonball Value Guide

These cast iron cannonballs represent a pivotal era in 19th-century artillery, serving as primary projectiles from the 1800s through the American Civil War. They are highly collectible due to their direct connection to historic battlefields and the transition from solid shot to advanced explosive shells.

What affects the value of Cast Iron Cannonball?

• Surface condition, specifically the severity of rust and whether the piece has been professionally conserved to prevent further decay.
• Historical provenance, such as documentation linking the projectile to a specific 19th-century battlefield or historic site.
• The presence of clear casting marks or unique manufacturing irregularities that indicate early production methods.
• The overall size and weight, as larger or rarer caliber shot typically commands a higher price within the $75-$150 range.

How to Identify Cast Iron Cannonball?

• Look for a distinct raised casting seam encircling the sphere where the two mold halves met during the hand-pouring process.
• Examine the surface for authentic age-related pitting and oxidation patterns consistent with 19th-century iron production.
• Verify the weight and diameter to ensure they match standard military calibers used in United States or European artillery of the era.
• Check for a 'sprue' mark or a small flat spot where the molten iron was originally poured into the mold.

History of Cast Iron Cannonball

Cast iron cannonballs were produced from the 17th through 19th centuries for use in artillery. Early examples were cast in molds and often show a seam where the two mold halves met; surface irregularities, pitting, and rust are common on recovered pieces. Such shot were used by militaries worldwide and were later supplanted by explosive shells and more advanced ammunition. Intact examples come from battlefields, training ranges, and historic sites and are collected as military antiques and archaeological artifacts.
