7 Rare Coins From The ’90s That Only Coin Collectors Know About

Coin collecting is more than just a hobby—it’s a fascinating journey through history, filled with surprises and hidden treasures. While many collectors focus on coins from the early 20th century or even older, some of the most valuable and rare finds come from the 1990s. This decade produced several U.S. coins with minting errors and design variations that have since become highly sought after.

From Lincoln cents with doubled dies to Roosevelt dimes missing clad layers, these modern rarities often go unnoticed in everyday change. Whether you’re a seasoned numismatist or just starting your collection, knowing what to look for can help you spot valuable coins hiding in plain sight. In this article, we’ll explore 7 rare coins from the ’90s that only serious collectors know about—and you might be lucky enough to find one in your own pocket or coin jar.

1. 1990 No “S” Lincoln Cent

The 1990 No “S” Lincoln Cent is one of the most famous mint errors from the decade. Normally, proof coins minted at the San Francisco Mint have a small “S” mintmark beneath the date. However, a few 1990 proof Lincoln cents were accidentally struck without this mark. These rare coins were still part of the proof sets intended for collectors, which makes the error even more surprising.

Because they were only discovered after release, most of these coins were already in private hands by the time the mistake was found. This rare cent has become a true treasure for error coin collectors and is extremely valuable. In top condition, it can fetch thousands of dollars. The rarity comes not only from the missing mintmark but also because very few of these coins exist, especially in pristine Proof 69 or 70 grades. It’s a standout coin that many collectors hope to find in old proof sets.

2. 1992 Close AM Lincoln Cent

The 1992 Close AM Lincoln Cent is one of the most exciting modern rarities in American numismatics. On standard Lincoln cents made for circulation in 1992, the letters “A” and “M” in “AMERICA” on the reverse are spaced apart—this is known as the “Wide AM.” However, some cents were mistakenly struck with a reverse die intended for the 1993 design, where the “A” and “M” are much closer together.

This die variety is called the “Close AM.” The error is barely noticeable to the untrained eye, but collectors pay top dollar for it. Only a handful of these coins have been found, making them extremely rare. A 1992 Close AM cent in excellent condition can sell for over $10,000. Because this variety can appear in ordinary pocket change, it’s a favorite target for coin hunters. Careful examination with a magnifying glass is usually needed to tell the difference.

3. 1995 Doubled Die Lincoln Cent

The 1995 Doubled Die Lincoln Cent is one of the most well-known doubled die errors of the modern coin era. This coin features a clear doubling on the obverse, especially visible in the word “LIBERTY” and the phrase “IN GOD WE TRUST.” Unlike many other error coins, this one was widely circulated before collectors realized the mistake, which makes it easier to find than others on this list—but condition is key.

Lower-grade examples might be worth only a few dollars, but uncirculated coins with a strong doubled image can be worth hundreds. PCGS and NGC have authenticated many examples, but the total number is still small compared to the total coins produced that year. Because of its bold and noticeable doubling, the 1995 doubled die has become a staple in modern error coin collections and remains a favorite among new collectors and seasoned experts alike.

4. 1999 Wide AM Lincoln Cent

The 1999 Wide AM Lincoln Cent is another fascinating and valuable error that collectors are always searching for. In most 1999 cents, the reverse has a “Close AM” design where the letters “A” and “M” in “AMERICA” are very close together, almost touching. However, a small number of 1999 cents were mistakenly struck with the “Wide AM” reverse intended for proof coins, where the letters have a noticeable space between them.

This is the opposite situation of the 1992 Close AM cent and is just as valuable. Collectors discovered this rare variety years after it entered circulation, so many remain hidden in coin jars and old rolls. In high-grade uncirculated condition, the 1999 Wide AM cent can bring in several hundred dollars or more, especially if graded by a top-tier service like PCGS. It’s another example of how small design differences can lead to big discoveries in coin collecting.

5. 1997 Double-Ear Lincoln Cent

The 1997 Double-Ear Lincoln Cent is a lesser-known but intriguing variety among error coin collectors. This coin features what appears to be a second ear lobe on Lincoln’s portrait due to a doubled die strike. While not as dramatic as some other doubled dies, it’s still clearly visible under magnification and has gained attention over time.

These types of errors happen when the die used to strike the coin shifts slightly during the engraving process, causing certain parts of the design to appear doubled. Although not as famous as the 1995 doubled die cent, the 1997 Double-Ear variety is significantly rarer and harder to find in circulation. Collectors who specialize in Lincoln cents actively look for this piece, and in high mint-state grades, it can command prices over $100. This coin demonstrates how even subtle errors can become sought-after collectibles when rarity and collector interest align.

6. 1998 Wide AM Lincoln Cent

The 1998 Wide AM Lincoln Cent is another coin with a reverse design mismatch similar to the 1999 variety. In 1998, the U.S. Mint accidentally used the proof reverse die (with a wide spacing between the “A” and “M” in “AMERICA”) for a small number of circulation coins. While this error might seem minor, it’s a major find for error collectors. Only a few of these coins were produced, and even fewer have been found in high-grade condition.

The Wide AM cents from 1998, 1999, and 2000 are often grouped together by collectors seeking rare transitional varieties. Because most people don’t check for this specific detail, many Wide AM cents likely remain unnoticed in everyday change. Coins with a clear Wide AM pattern, especially when graded MS65 or higher, can be worth hundreds. The 1998 version is slightly more common than the 1999 one, but it’s still a rare gem in the world of modern coin errors.

7. 1996 Roosevelt Dime Missing Clad Layer

The 1996 Roosevelt Dime Missing Clad Layer is a striking and unusual error coin that visually stands out. Normally, Roosevelt dimes are made of a copper core with an outer layer of copper-nickel, giving them a silver appearance. However, some 1996 dimes were struck without this outer layer, exposing the copper core and giving the coin a distinct bronze color.

This type of mint error occurs when the metal strip used to make the blanks is improperly prepared, leading to a coin that lacks its normal clad appearance. These coins are often lighter in weight than standard dimes and have a unique look that’s easy to spot. While missing clad layer errors can occur in other years too, the 1996 dime version is one of the better-known examples. Depending on the condition and how much of the clad layer is missing, these coins can sell for anywhere from $100 to several hundred dollars.

Bottom Line

The 1990s produced some of the most intriguing and valuable modern coin errors and varieties. Whether it’s the 1990 No “S” Lincoln cent or the 1999 Wide AM, these rare coins are worth far more than face value and can command high prices among collectors.

The key to finding these treasures lies in attention to detail—small design differences can make a huge impact on value. So before spending your spare change, take a closer look. You never know when you might discover a hidden gem that could be worth hundreds or even thousands of dollars.
