Civil War Cannonball Value Guide

Period
1861-1865
Origin
United States
Materials
Cast Iron

This solid shot cannonball is a quintessential artifact of the American Civil War, serving as a primary kinetic energy projectile for both Union and Confederate artillery. These cast iron spheres were engineered to demolish fortifications and disrupt enemy formations, representing a pivotal era in 19th-century military technology.

What affects the value of Civil War Cannonball?

  • Condition of the iron, specifically the level of corrosion or 'scaling' that can obscure the original surface.
  • Provenance and recovery site, as balls found at major battlefields often command higher collector interest.
  • The specific weight and size, with less common calibers sometimes fetching a premium over standard 12-pounders.
  • Evidence of professional conservation to stabilize the iron and prevent further rusting or deterioration.

How to Identify Civil War Cannonball?

  • Verify the weight of the projectile to match standard period calibers, such as the common 6-pounder or 12-pounder designations.
  • Inspect the surface for a casting seam or a 'sprue' mark, which indicates the iron was poured into a mold.
  • Check for signs of authentic oxidation and pitting consistent with 150-year-old cast iron rather than modern reproductions.
  • Confirm the diameter using calipers to ensure it aligns with historical bore sizes for smoothbore cannons.

History of Civil War Cannonball

During the American Civil War (1861-1865), cannonballs like this were a primary form of artillery ammunition. Solid shot cannonballs were designed for their kinetic energy, used to smash through fortifications, dismast ships, or create lanes through enemy formations. They were typically cast from iron and varied in weight, designated by the weight of the projectile, such as 6-pounder or 12-pounder. The evolution of artillery during this period, including the introduction of rifled cannons and more advanced projectiles like shells and grapeshot, eventually reduced the prominence of simple solid shot, but they remained a staple throughout the conflict.
