M1917 Kelly Helmet Value Guide

The M1917 Kelly Helmet is a cornerstone of American military history, serving as the primary headgear for the US Army during the Great War. Based on the British Brodie Mark I design, this 'Doughboy' helmet was specifically engineered to protect soldiers from lethal overhead shrapnel in trench warfare.

What Is M1917 Kelly Helmet Worth?

The typical price range for M1917 Kelly Helmet is $135 - $150 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The presence and condition of the original cork-infused paint significantly impacts the $135-$150 price range.
• Intact original leather liners and chinstraps are rare and command the highest collector premiums.
• Unit markings or hand-painted divisional insignias on the front of the shell can exponentially increase value over base prices.
• Structural integrity, including the absence of major dents or heavy oxidation on the manganese steel alloy.

How to Identify M1917 Kelly Helmet?

• Look for the distinctive textured finish created by cork-infused olive drab paint applied to the manganese steel shell.
• Examine the interior for a heat stamp number usually located on the underside of the rim to verify American production.
• Check the liner system for a leather headband and a black oilcloth crown held together by a tubular steel rivet.
• Verify the chinstrap is made of vegetable-tanned leather with a sliding steel buckle, unlike the later M1917A1 canvas versions.

History of M1917 Kelly Helmet

Adopted by the United States in 1917, this helmet was based on the British Brodie Mark I design. It was created to protect soldiers from overhead shrapnel during trench warfare. While the British version used Manganese steel, the American M1917 was made from a slightly different alloy and remained the standard US helmet until the introduction of the M1 in 1941.
