Current Market Value of a Thompson

While prices can vary, a typical semi-automatic Thompson is worth around $1,100, with a general range between $900 on the low end to as high as $1400. On the other hand, a fully-automatic NFA Thompson generally ranges between $15,000 on the low end, all the way up to $120,000 for an early Colt Thompson submachine gun.

History of the Thompson

The Thompson submachine gun, a.k.a. the Tommy Gun was designed by John T. Thompson in 1917 for use in the trenches of World War I. The design was finally patented in 1920; two years after the end of the war. The gun was then marketed to the general public due to a lack of purpose.

In the early 1920’s, the M1921 model Thompson was advertised as a civilian gun and was readily available­­—  you could walk into a hardware store and get one, but it was quite expensive. During this time period the Great Prohibition was happening and with its unique look and fully automatic capability, it didn’t take long for well-funded organized crime groups in Chicago to take a liking to the new gun. Law Enforcement also found it effective due to its rapid firing capability and soon started using it too. It earned the nickname ‘Chicago Typewriter' because it sounded like one when fired. Famous criminals like Al Capone and John Dillinger as well as famous detectives like Elliot Ness used the Thompson, adding to the mystique and wow factor.

As the decade rolled on, new variants came out, like the iconic M1928. Later, in service, other variants, like the M1A1—which went on to become a World War 2 legend—were introduced. The Thompson's service history is proof of its excellence in design; it saw about 50 years of useful service, from the 1920s all through to the Vietnam War.

How We Calculate Used Thompson Values

The market value of a Thompson submachine gun is determined by factors such as its condition, specific model, unique modifications, and special editions, with its historical significance and iconic status appealing to collectors seeking a connection to the Tommy Gun's enduring legacy.

How We Appraise Thompson Models

From its time as a street-sweeping gangster gun to a fast-firing legend of the battlefield, there have been many different variations of the Thompson submachine gun. Whichever model you are looking for and for whatever purpose, it is important to understand the differences between each model.

M1921, 1927, and M1928

The M1921 is the first and original model of the Thompson submachine gun. This model was originally planned to be a “trench broom” for World War 1 but never reached active service. It carried the original silhouette, which became well-known as the ‘Tommy Gun’— a blued steel finish, trademark drum magazine, iconic vertical foregrip, ridged barrel, and the signature “Cutts” Compensator for reduced recoil.

The gun chambered the .45 ACP giving it a kick and was favored by both gangsters and law enforcers. This formula served as the blueprint for all Thompson variants to come out of this decade— the 1927 model being the semi-automatic version aimed for civilian use, and the M1928 a.k.a. “Chicago Typewriter” which was visually the same but had upgraded internal parts to make it an even more efficient tool for both the mafia and police alike.

This era of the Thompson submachine gun rings very highly with collectors and enthusiasts because of its significance as an icon of an equally iconic decade— it captures the style, drama, and action of the roaring 20’s. An original production M1921 can cost anywhere between 50,000 USD to upwards of 120,000 USD and an M1928 can fetch anywhere between 30,000 USD to upwards of 60,000 USD.

M1/M1A1

In the latter part of the 1930’s, the Thompson submachine gun was adopted by the U.S. Military; they had modified the M1928 ditching the vertical fore grip for a more simple horizontal wooden handgrip. This was to reduce the cost and weight of the weapon. Having officially joined World War 2 after the bombing of Pearl Harbor in 1941, the military had then made further modifications to simplify the design and thus came up with the M1 and M1A1 models.

Both models lost the ‘Cutts’ Compensator, a trademark of the original Tommy gun. The M1 had a simple L-shaped rear sight, while the M1A1 had a steel hood for better aiming and further internal improvements to make production much cheaper. This variant of the Thompson was usually assigned to patrol leaders and Non-Commissioned Officers.

Its historical significance as a weapon during the Second World War gives it a very high collector's appeal, and military markings further augment the value of the Thompson during one of the most pivotal eras in modern history. Values of actual examples from this time period can range from 25,000 USD to upwards of 50,000 USD depending on the condition.

How Finish Affects Value

Having one of the most recognizable and iconic designs in the gun world, the Thompson takes it a step further with a whole host of different finishes available combined with materials like wood for the grips and stock which add a level of craftsmanship.

The Thompson submachine gun's finish varies based on its intended use. Original models from the 20’s featured a classic blued finish, prized for its deep, rich appearance and corrosion resistance. Military variants, particularly those used in WWII, adopted a parkerized finish valued for its matte, non-reflective properties in combat situations.

Later productions and special editions introduced finishes like nickel plating, stainless steel, and even rare gold plating, but these are not typical of original Thompsons. For collectors and enthusiasts, the authenticity of the finish—blued for early models and parkerized for military versions— often plays a significant role in determining a Thompson's historical value and appeal.

Condition and Value

The Thompsons “want-one” factor does not solely lie on its historical importance but also in the different conditions they come in. Some may be pristine and so well-preserved and others may bear some dings and scratches throughout its useful life.
