Collectors Dropped Over $90K on Tommy Guns in April — Here’s What Sold on GunBroker

Tommy guns have long held a legendary place in American firearms history — from their infamous role in Prohibition-era crime to their respected service in World War II. Tommy guns remain some of the most iconic and collectible firearms in the U.S., and their value continues to rise among enthusiasts. April 2025 saw a trio of historic full-auto Thompsons auctioned off on GunBroker, each drawing significant bids from across the country. Below are the top three most expensive Tommy guns sold last month.

Included in April’s Most Expensive Tommy Guns Report is one of the most coveted variants ever made — the Colt 1921 / 1928 U.S. Navy Thompson SMG. This highly collectible hybrid model, combining features from both the 1921 and 1928 designs, is factory-marked with “U.S. Navy” and was sold in pristine, factory-new condition. Its rarity and exceptional quality sparked aggressive bidding, ultimately earning it the top spot as April 2025’s most expensive Tommy gun sold on GunBroker.

Another standout, featured in the #2 position, is a classic Colt 1928 Thompson with the iconic U.S. Navy overstamp. This transferable, fully automatic model is a textbook example of WWII-era craftsmanship and remains a top choice for serious collectors seeking historical accuracy and value.

Rounding out the top three is the Auto-Ordnance 1928A1 Thompson .45 Full Auto SMG — a battle-proven, full-auto wartime model. Despite being listed in used condition, this Thompson still commanded a premium price, proving that authentic, operable examples of the 1928A1 remain in high demand in today’s machine gun collector market.
