1894-S Barber Dime
The 1894-S Barber Dime is one of the most legendary coins in U.S. history. Only 24 of these dimes were ever minted at the San Francisco Mint, and fewer than 9 are known to still exist. Its rarity, combined with the mystery of its creation, makes it one of the most valuable dimes ever produced.
How to Identify It:
Check the reverse side for the “S” mint mark. The coin features Liberty’s profile with a laurel wreath on her head—a classic Barber design. Because of its scarcity, this dime is often faked, so professional grading is necessary for authentication.
1916-D Mercury Dime
This dime was minted in Denver and marks the first year of the Mercury dime series. With only 264,000 coins produced, it’s considered a key date among collectors. It’s not as rare as the 1894-S, but still extremely valuable—especially in high-grade condition.
Key Features:
Look for the “D” mint mark on the reverse. Coins in excellent condition can fetch six-figure prices, especially if professionally graded by PCGS or NGC. This dime is widely sought after because of its low mintage and historical relevance.
1975 No-S Roosevelt Dime
This coin is a prime example of a modern minting error that turned into a collector’s jackpot. Intended for proof sets made in San Francisco, two of these dimes were mistakenly struck without the “S” mint mark.
How to Spot It:
Most proof coins should have an “S” mint mark. If it’s missing on a 1975 dime, you could have one of the two known examples. Due to the extremely limited number, this coin is worth nearly half a million dollars and requires expert authentication.
1968 No-S Roosevelt Dime
Similar to the 1975 No-S dime, this coin also features a missing mint mark. In this case, a few 1968 proof coins were mistakenly struck at the San Francisco Mint without the identifying “S” mark.
Identification Tips:
Check for the missing mint mark on the reverse side. These are only valuable if they are proof coins, not business strikes. High-grade examples are especially valuable and can bring in tens of thousands of dollars at auction.
1942/1 Mercury Dime
This error coin occurred during a time of war, when old dies were reused and created an overdate. On this coin, the “1” from 1941 can be seen beneath the “2” of 1942.
How to Identify It:
Use a magnifying glass to examine the date closely. You should see a faint “1” underneath the “2.” Though not as rare as others, this dime is highly collectible and can be worth thousands depending on condition.
The Bicentennial Quarter: More Than Just a Commemoration
In 1976, the U.S. Mint released the Bicentennial Quarter to celebrate 200 years of American independence. These quarters featured a unique reverse design with a colonial drummer, and millions were produced.
Standard Bicentennial Quarters:
Most of these coins are only worth face value, especially in circulated condition. However, silver-clad versions and uncirculated specimens are worth more.
Rare Bicentennial Quarter Errors:
Some quarters were struck with double die errors, off-center images, or missing mint marks. These types of mistakes can significantly raise the coin’s value, sometimes to thousands of dollars. If you have one, professional grading is advised.
How to Check If You Own a Rare Coin
Wondering if your coin is worth something? Follow these steps to find out:
- Examine the Date: Certain years are key indicators of rare coins.
- Look for Mint Marks: “D” for Denver, “S” for San Francisco, and “P” or no mark for Philadelphia.
- Check for Errors: Double dies, missing mint marks, and off-center strikes are valuable clues.
- Use Magnification: Small details can separate a valuable coin from a common one.
- Get It Graded: Services like PCGS or NGC can officially verify and rate your coin.
Keeping your coin in good condition is also important. Handle with care, avoid cleaning, and store in a safe, dry place.
Investing in Rare Coins
Should You Invest in Coins?

Tips for Investing in Coins:
- Buy from Reputable Dealers: This ensures authenticity.
