The 1937-D 3-Legged Buffalo Nickel is one of the most famous and valuable error coins in U.S. numismatics. Worth $500 to $50,000 depending on grade, this coin was created when an over-polished die at the Denver Mint accidentally removed the front right leg of the buffalo from the coin’s design. The result is a buffalo that appears to stand on only three legs — a dramatic and instantly recognizable error that collectors have pursued passionately for nearly 90 years.
This guide covers everything you need to know about the 1937-D 3-Legged nickel: how the error occurred, current market values across all grades, how to authenticate genuine examples, and how to avoid the many counterfeits that flood the market.

How the 3-Legged Error Was Created
The story behind the 1937-D 3-Legged Buffalo Nickel involves a routine maintenance error at the Denver Mint. During production, coin dies occasionally clash — meaning the obverse and reverse dies strike each other without a planchet between them, transferring faint impressions of each die onto the other. When this happened to a reverse die in 1937, a mint worker attempted to remove the clash marks by polishing the die surface.
The polishing was too aggressive. In the process of removing the clash marks, the worker ground away the details of the buffalo’s front right leg entirely. The die was then returned to the press and continued striking coins. Thousands of nickels were produced before the error was detected and the die was finally pulled from service.
The excessive die polishing also created other telltale signs that help authenticate genuine examples. The area beneath the buffalo’s body shows unusual smoothness, and the overall reverse design appears slightly softer than a normal 1937-D nickel. These characteristics, combined with the missing leg, form the authentication fingerprint that experts use to verify genuine specimens.

1937-D 3-Legged Buffalo Nickel Value Chart
Values for the 1937-D 3-Legged nickel have risen steadily over the past two decades as the coin’s fame has grown and the supply of high-grade examples has thinned. Here are current market values across the grading spectrum.
| Grade | PCGS/NGC Certified Value | Raw (Ungraded) Value |
|---|---|---|
| Good (G-4 to G-6) | $600 – $900 | $400 – $700 |
| Very Good (VG-8 to VG-10) | $800 – $1,200 | $600 – $900 |
| Fine (F-12 to F-15) | $1,200 – $2,000 | $900 – $1,500 |
| Very Fine (VF-20 to VF-35) | $2,000 – $4,000 | $1,500 – $3,000 |
| Extremely Fine (EF-40 to EF-45) | $4,000 – $8,000 | $3,000 – $6,000 |

| Mint State (MS-64 to MS-65) | $35,000 – $100,000+ | N/A — always certified |
The significant price gap between certified and raw coins reflects the prevalence of counterfeits in the market. Buyers strongly prefer PCGS or NGC authenticated examples because the risk of purchasing a fake is eliminated. This certification premium makes grading a genuine 1937-D 3-Legged nickel one of the best investments in numismatics.
How to Authenticate a 1937-D 3-Legged Buffalo Nickel
The 1937-D 3-Legged Buffalo Nickel is one of the most counterfeited coins in the hobby. Fakes are created by filing or acid-etching the leg off a normal 1937-D nickel. Learning the three key authentication markers will protect you from purchasing an altered coin.
Marker 1: The Moth-Eaten Rear Leg
On a genuine 3-Legged nickel, the same die polishing that removed the front leg also partially affected the rear leg. The back right leg of the buffalo shows a distinctive rough, pitted appearance — often described as “moth-eaten.” If the rear leg looks completely normal and smooth, the coin is likely a fake where someone simply removed the front leg by hand.
Marker 2: The Smooth Belly
Die polishing removed fine details from the area beneath the buffalo’s body. On a genuine example, the belly area appears smoother and less detailed than a normal 1937-D nickel. The transition from the missing leg area to the belly should flow naturally rather than showing any abrupt edges that would indicate physical alteration.
Marker 3: The Stream of Metal (Die Polishing Lines)
Many genuine 3-Legged nickels show faint parallel lines or a streaming effect on the reverse, particularly near the missing leg area. These are artifacts of the die polishing process. Counterfeit coins created by filing or etching will not show these characteristic lines.
When spending more than a few hundred dollars on this coin, always insist on PCGS or NGC certification. The grading fee is a tiny fraction of the coin’s value and provides definitive authentication.

Why This Coin Keeps Appreciating
Several factors drive the sustained appreciation of the 1937-D 3-Legged Buffalo Nickel. First, the population is fixed — no more will ever be produced, and the number of surviving examples slowly decreases as coins are lost, damaged, or permanently placed in collections. Second, the Buffalo Nickel series is one of the most popular in all of American numismatics, and the 3-Legged variety is its most famous coin. Third, the error has a compelling story that attracts non-collectors and general investors to numismatics.
Over the past 20 years, values across all grades have approximately doubled, with the strongest appreciation in higher grades (EF and above) where surviving populations are smallest. This trend is likely to continue as the coin’s fame grows and the collecting base expands internationally.

Where to Buy and Sell the 1937-D 3-Legged Nickel
Because of the counterfeiting risk, always buy this coin certified by PCGS or NGC. Reputable sources include Heritage Auctions (for higher-grade examples), eBay (filter for PCGS/NGC certified only), major coin shows like the ANA World’s Fair of Money, and established online dealers who specialize in error coins. Avoid purchasing raw, uncertified examples unless the price reflects the authentication risk.
If you own a genuine 1937-D 3-Legged nickel and want to sell, getting it certified first will typically increase the sale price by 20-40% over what a raw coin would bring. The combination of authentication certainty and professional grading gives buyers confidence and drives competitive bidding at auction.
