Colt .31 Caliber Bullet Mold Value Guide

This antique brass bullet mold is a vital accessory for the Colt .31 caliber percussion revolvers, which were the quintessential 'pocket' pistols of the mid-19th century. Its dual-cavity design allowed owners to cast both round balls and conical bullets, making it an essential piece of kit for personal defense during the American Civil War era.

What Is Colt .31 Caliber Bullet Mold Worth?

The typical price range for Colt .31 Caliber Bullet Mold is $250 - $350 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Overall tightness of the hinge and alignment of the two brass halves when closed.

How to Identify Colt .31 Caliber Bullet Mold?

• Look for the 'COLTS PATENT' stamping clearly visible on the top of the brass block.
• Verify the presence of two distinct cavities: one for a round lead ball and one for a conical projectile.
• Check for the small '31' caliber marking often found on the side or near the hinge of the mold.
• Examine the iron sprue cutter for authentic mid-19th century wear and a secure attachment screw.

History of Colt .31 Caliber Bullet Mold

During the mid-19th century, firearms like Colt's percussion revolvers required users to cast their own ammunition from lead. Bullet molds were essential tools for owners of these firearms, allowing them to produce the necessary lead projectiles for their pistols. These molds were often issued with the firearms or purchased as separate accessories. The .31 caliber was popular for smaller 'pocket' revolvers, widely used for personal defense and as a secondary weapon during the American Civil War era and beyond.
