Few U.S. coins have captured collectors’ attention quite like the 1937-D 3-Legged Buffalo Nickel. At first glance, it may look like an ordinary Buffalo Nickel, but a closer inspection reveals one of the most famous mint errors in American coin history. Instead of four visible legs, the buffalo appears to be standing on only three, creating a dramatic variety that has fascinated collectors for decades.
If you think you’ve found one, proper identification is essential. Genuine examples are scarce, highly sought after by collectors, and frequently counterfeited or altered, making careful authentication especially important. Understanding the diagnostics can help you avoid costly mistakes and determine whether your coin deserves professional authentication.
Quick Answer
The 1937-D 3-Legged Buffalo Nickel is a well-known die variety produced at the Denver Mint. The missing front leg was not caused by circulation wear but by excessive polishing of a damaged reverse die before additional coins were struck. Today, authenticated examples are among the most desirable Buffalo Nickels, with value depending on authenticity, grade, eye appeal, and current collector demand.
Collectors who are new to the Buffalo Nickel series should also read our Buffalo Nickel Value Guide: Rare Dates, Mint Errors & Collector Tips, where we explain the history of the series, important dates, and what makes certain nickels especially collectible.
Because this variety is one of the most frequently altered Buffalo Nickels, collectors should never rely on the missing leg alone when identifying a genuine example. Professional authentication remains the safest way to confirm authenticity before buying, selling, or assigning value.
Why Is the 1937-D 3-Legged Buffalo Nickel So Famous?
Unlike many collectible coins that owe their rarity to low mintages, the 1937-D 3-Legged Buffalo Nickel became famous because of an error that occurred during the minting process.
During production at the Denver Mint, a reverse die developed clash marks and damage. To prepare it for continued use, mint employees aggressively polished the die. Unfortunately, too much metal was removed from the die surface, eliminating much of the buffalo’s front right leg. Coins struck afterward displayed the now-famous “three-legged” appearance.
Because the error was quickly corrected after it was discovered, relatively few examples entered circulation compared with normal 1937-D Buffalo Nickels.
How to Identify a Genuine 1937-D 3-Legged Buffalo Nickel
Correct identification is essential because altered Buffalo Nickels are commonly modified to imitate this famous die variety.
Check the Date
The obverse should display the date 1937.
Many ordinary Buffalo Nickels from other years have been altered by removing part of a leg, but only the genuine 1937-D variety has the correct combination of diagnostics.
Verify the Mint Mark
Turn the coin over and look beneath the words FIVE CENTS.
A genuine example carries a D mint mark indicating production at the Denver Mint.
Examine the Buffalo Carefully
The most obvious feature is the missing front right leg.
However, experienced collectors never rely on this characteristic alone.
Authentic coins also display:
- A smooth transition where the missing leg should appear
- Distinct polishing lines in the area beneath the buffalo
- Remaining hoof detail on the ground
- Other reverse characteristics consistent with the known die variety
These diagnostics help distinguish genuine examples from damaged or altered coins.

Is It Really Missing a Leg?
Not exactly.
One of the biggest misconceptions among beginners is that the buffalo somehow lost its leg during circulation.
In reality, the leg disappeared because the die itself was over-polished before striking additional coins. Since every coin struck from that damaged die inherited the same missing design element, the variety is classified as a genuine mint-made die variety rather than post-mint damage.
This distinction is extremely important because coins with legs that have simply worn away through circulation are not the famous 3-Legged variety.
Common Misidentification Mistakes
Collectors frequently mistake damaged Buffalo Nickels for the genuine error.
Some of the most common mistakes include:
- Assuming any worn Buffalo Nickel is the 3-Legged variety.
- Confusing heavy circulation wear with a mint-made die variety.
- Buying altered coins without professional authentication.
- Ignoring other diagnostic features besides the missing leg.
A genuine 1937-D 3-Legged Buffalo Nickel shows multiple identifying characteristics that specialists use together rather than relying on a single feature.

Why Authentication Matters
The popularity of the 1937-D 3-Legged Buffalo Nickel has led to countless altered coins entering the marketplace.
Some individuals intentionally grind away part of the buffalo’s leg to imitate the famous variety. While these alterations may fool inexperienced collectors, they usually lack the correct die markers and polishing characteristics seen on authentic examples.
Professional authentication by respected grading services such as PCGS or NGC provides independent confirmation of authenticity and helps reduce uncertainty when buying or selling.
In the next section, we’ll look at the specific die diagnostics experts use, how grading affects desirability, what influences market value, and practical buying and selling tips for collectors.
How Experts Authenticate a Genuine 1937-D 3-Legged Buffalo Nickel
Professional graders never identify this famous variety by looking only at the missing leg. Instead, they examine a combination of well-known diagnostics that have been documented for decades.
A genuine example should display several of these characteristics together.
1. The Missing Front Right Leg
The buffalo’s front right leg is almost entirely absent. Instead of appearing broken or worn away, the area looks smooth because metal was removed from the working die before the coin was struck.
2. Remaining Hoof Detail
Although the leg is missing, a portion of the hoof can often still be seen resting on the ground beneath the buffalo. This is one of the classic diagnostics that helps distinguish authentic coins from altered examples.
3. Polishing Lines
Heavy die polishing left visible polishing marks beneath the buffalo’s belly and around the missing leg area. These lines are part of the die itself and appear on genuine examples regardless of grade, although they may become harder to see on heavily worn coins.
4. Reverse Die Markers
Specialists also examine other reverse features that match the known die variety. These diagnostics are difficult for counterfeiters to reproduce consistently, which is why professional authentication remains so important.
Common Counterfeits and Altered Coins
Because authentic 1937-D 3-Legged Buffalo Nickels are valuable, counterfeit and altered examples appear regularly in the marketplace.
Some altered coins are created by:
- Grinding away one of the buffalo’s legs.
- Filing the design to imitate the missing leg.
- Modifying an ordinary 1937-D Buffalo Nickel.
- Altering coins from different dates.
These pieces usually lack the proper die polishing characteristics and other known diagnostics used by grading experts.
If there’s any uncertainty about a coin’s authenticity, professional certification is the safest course of action.
Does Condition Affect Value?
Absolutely.
Although every genuine 1937-D 3-Legged Buffalo Nickel is considered desirable, condition plays a major role in determining collector demand.
Professional grading considers several characteristics that influence both collector appeal and market value, including:
| Grading Factor | Why It Matters |
|---|---|
| Wear | Less circulation wear generally increases collector appeal. |
| Strike Quality | Sharper design details are preferred. |
| Surface Preservation | Original, undamaged surfaces are highly desirable. |
| Luster | Mint luster adds value on uncirculated examples. |
| Eye Appeal | Attractive color and overall appearance can influence demand. |
| Certification | Authenticated coins are generally easier to buy and sell. |
Because this variety circulated extensively before collectors recognized its significance, high-grade survivors are much less common than worn examples.
What Determines Its Market Value?
There is no universal price for a 1937-D 3-Legged Buffalo Nickel.
Instead, collectors evaluate several factors together:
- Authenticity
- Professional certification
- Grade
- Surface originality
- Eye appeal
- Current collector demand
- Recent auction results
Completed auction sales generally provide a more accurate picture of market demand than unsold asking prices because they reflect actual transactions between buyers and sellers.
Two coins assigned the same numerical grade may still bring different prices depending on strike quality, toning, and overall appearance.
For this reason, experienced collectors often review recent certified auction records rather than relying on asking prices from online listings.
Buying Tips for Collectors
If you’re hoping to add this famous variety to your collection, patience and careful research are essential.
Keep these guidelines in mind:
- Buy certified examples whenever possible.
- Purchase from reputable coin dealers or established auction houses.
- Compare multiple certified coins before making a decision.
- Learn the major diagnostics before shopping.
- Be cautious of bargains that seem too good to be true.
Many experienced collectors prefer waiting for a properly authenticated example rather than taking unnecessary risks with uncertified coins.

Yes. The 1937-D 3-Legged Buffalo Nickel is a genuine and well-documented U.S. Mint die variety.

It is recognized by major grading services, including PCGS and NGC.
How can I tell if my coin is genuine?
The missing leg alone is not enough to confirm authenticity. Genuine examples display several known diagnostics, including the correct Denver mint mark, specific die-polishing characteristics, remaining hoof detail, and other reverse die markers. Because altered coins are common, professional authentication is strongly recommended for any suspected example.

No. Most 1937-D Buffalo Nickels are normal issues without the famous variety. Only authenticated examples of the 3-Legged die variety command significant collector interest.
Should I clean my Buffalo Nickel?
No. Cleaning can permanently damage a coin’s original surfaces and reduce its desirability to collectors. Even if a coin appears dirty or toned, leaving it in its original condition is generally the best choice.
Does certification matter?
Yes. Certification by recognized grading services such as PCGS or NGC confirms both authenticity and grade. Since the 1937-D 3-Legged Buffalo Nickel is one of the most frequently altered U.S. coins, certification provides confidence for both buyers and sellers.
