1. 1990 No-S Proof Lincoln Cent: The Rare Ghost Mintmark
The 1990 No-S Proof Lincoln Cent is one of the most notable and sought-after coins from the 1990s. Normally, proof coins minted at the San Francisco Mint carry an “S” mintmark, indicating their origin. However, a small number of these 1990 proof Lincoln cents were struck without the mintmark, making them extremely rare and valuable.
Value
These coins can range in value from $2,000 to $3,000 depending on their condition. Coins graded at PR69 or higher can be worth considerably more.
How to Spot It
- Mintmark Check: Flip the coin over to check for the mintmark. If it’s absent, you may have a 1990 No-S proof coin.
- Proof Finish: These coins have a distinctive shiny, mirror-like surface and sharply defined features, which sets them apart from regular coins.
- Condition is Key: Higher-grade examples (PR69 or higher) are worth significantly more.
2. 1992 Close AM Lincoln Cent: A Collector’s Dream
The 1992 Close AM Lincoln Cent is one of the most coveted coins due to its striking error. The mint accidentally used a proof reverse die for a small number of business-strike coins, resulting in the “AM” in “AMERICA” being very close together—almost touching. This rare error makes it a must-have for collectors.
Value
Coins of this variety can fetch $20,000 or more in uncirculated condition, especially when they are in pristine form.
How to Spot It
- Examine the “AM”: The key feature is the tight spacing between the “A” and “M” in “AMERICA.” You’ll need a magnifying glass to see this clearly.
- Compare to a Standard Coin: When compared to a regular 1992 cent, the Close AM variety will have noticeably closer lettering.
- Look for Other Minting Errors: Some Close AM coins also feature other small errors that make them even rarer.
3. 1992-D Close AM Lincoln Cent: Denver’s Rare Find
Similar to the 1992 Close AM, the 1992-D Close AM Lincoln Cent was struck with the same error but at the Denver Mint. While fewer of these were produced, they are highly sought after and can command significant prices at auction.
Value
The value for this coin is comparable to the 1992 Close AM, often surpassing $20,000 when found in high grades.
How to Spot It
- Look for the “D” Mintmark: Unlike the Philadelphia-minted coin, this one will have a “D” mintmark beneath the date.
- Close AM Check: The spacing between the “A” and “M” will be noticeably tight, almost touching.
4. 1999 Wide AM Lincoln Cent: A Slightly Less Rare Find
The 1999 Wide AM Lincoln Cent features another unique error, where the “AM” in “AMERICA” is spaced too far apart. While not as rare as the Close AM coins, the Wide AM Lincoln Cent is still highly desirable for collectors and investors alike.
Value
Although it’s not worth as much as the Close AM coins, the 1999 Wide AM Lincoln Cent can still fetch hundreds of dollars in uncirculated condition.
How to Spot It
- Examine the Reverse: The “A” and “M” in “AMERICA” will have significantly wider spacing than on a regular coin.
- Comparison: Use a standard 1999 cent to compare the spacing and see the difference clearly.
Historical Context and Coin Production in the 1990s
Understanding the historical context of coin production in the 1990s adds another layer to your knowledge as a collector. The U.S. Mint was undergoing significant changes in the 1990s, adapting to new technologies and processes.
During this time, there was a focus on improving the quality of proof coins, and the Mint was also adjusting to modern minting techniques. Unfortunately, this led to a few mistakes, like the Close AM error, which resulted in some highly valuable and rare coins.
How Coin Grading Affects Value?
Coin grading is crucial in determining a coin’s value. The Sheldon Scale, which ranges from 1 to 70, is used to assign a grade based on the coin’s quality. The higher the grade, the more valuable the coin. Coins like the 1990 No-S Proof Lincoln Cent in PR69 or PR70 condition are far more valuable than coins with visible wear and tear.
When it comes to rare coins, collectors and investors will typically seek the highest grades possible. A coin’s grade can dramatically affect its market price, with higher-grade coins often fetching tens of thousands of dollars more than their lower-grade counterparts.
How to Protect and Store Rare Coins?
Protecting your rare coins is just as important as spotting them. Here are a few tips on how to store and preserve your collection:
- Use Acid-Free Holders: Store your coins in protective holders that are acid-free to prevent damage over time.
- Avoid Handling: Wear cotton gloves when handling coins to avoid getting oils and dirt from your fingers on the surface.
- Store in a Safe Place: Keep your valuable coins in a safe, preferably a bank safe deposit box, to protect them from theft or environmental damage.
How to Spot Counterfeits?
With valuable coins like these rare 1990s varieties, counterfeits are a concern. Here’s how you can spot a fake coin:
- Weight and Size: Compare the coin’s weight and size to that of a known authentic coin. Counterfeit coins may be off by a few grams.
- Mintmarks: Fake coins often have poorly stamped mintmarks or lack them altogether.
- Details and Finish: Counterfeit coins might have fuzzy details, particularly around the edges. A real coin will have sharp, clear details.
- Consult Experts: If you’re unsure, consult a professional numismatist or use a trusted grading service.

FAQs About 4 Coins From The ’90s That Are Rarely Seen Outside Collector Circles Worth Millions
1. What makes a 1990 No-S Proof Lincoln Cent so valuable?
The 1990 No-S Proof Lincoln Cent is valuable because it was struck without the typical “S” mintmark that indicates it was minted in San Francisco. This rare error has made the coin highly sought after by collectors. Its unique absence of the mintmark sets it apart from other proof coins of the same year.
2. How do I know if I have a 1992 Close AM Lincoln Cent?
To identify a 1992 Close AM Lincoln Cent, look closely at the “AM” in “AMERICA” on the reverse side. In this error coin, the “A” and “M” are unusually close together, nearly touching. A magnifying glass or jeweler’s loupe is useful for spotting this error.
3. Are all 1992 Close AM coins worth a lot of money?
Not all 1992 Close AM coins are worth the same. Their value is highly dependent on the coin’s condition. Coins in uncirculated or near-perfect condition can fetch over $20,000. Lower-grade coins may still have value but will not reach these high amounts.
4. How can I tell the difference between a 1992-D Close AM and a 1992 Close AM Lincoln Cent?
The main difference is the mintmark. The 1992-D Close AM Lincoln Cent has a “D” mintmark under the date, indicating it was minted in Denver. The 1992 Close AM, on the other hand, is minted in Philadelphia and does not have a mintmark.

Coin grading is the process of evaluating a coin’s condition, using a scale from 1 to 70. The higher the grade, the more valuable the coin.
