In-Depth Look at Each Coin
1894-S Barber Dime
History and Significance
The 1894-S Barber Dime is one of the most legendary coins in U.S. history. Only 24 were ever minted at the San Francisco Mint, and fewer than nine are known to exist today. The circumstances of its creation remain a mystery, adding to its allure.
How to Identify
Look for the “S” mint mark on the reverse and Liberty’s profile with a laurel wreath. Authenticity is crucial—many fakes exist, so professional grading is essential.
1916-D Mercury Dime
History and Significance
This dime marks the debut of the Mercury dime series and was minted in Denver. With only 264,000 produced, it is a key date for collectors.
How to Identify
Check for the “D” mint mark on the reverse. High-grade examples can fetch six-figure sums, especially if professionally graded.
1975 No-S Roosevelt Dime
History and Significance
A modern minting error, this dime was intended for proof sets at the San Francisco Mint but was struck without the “S” mint mark. Only two are known to exist.
How to Identify
Proof coins should have an “S” mint mark. If it’s missing on a 1975 dime, you may have one of the rarest modern U.S. coins.
1968 No-S Roosevelt Dime
History and Significance
Similar to the 1975 No-S dime, this coin is a proof coin missing the “S” mint mark. Fewer than 20 are known.
How to Identify
Look for the missing mint mark on the reverse. Only proof coins are valuable in this context.
Bicentennial Quarter (Error Versions)
History and Significance
Released in 1976 to celebrate 200 years of American independence, most Bicentennial Quarters are worth face value. However, error versions—such as double dies, off-center strikes, or missing mint marks—can be worth thousands or, in rare cases, millions.
How to Identify
Check for unusual features or minting errors. Professional grading is recommended for authentication.
How to Spot and Authenticate Rare Coins
Examine the Date and Mint Mark
Certain years and mint marks are key indicators of rarity. For example, the “S” on the 1894-S Barber Dime or the “D” on the 1916-D Mercury Dime.
Check for Errors
Double dies, missing mint marks, and off-center strikes are valuable clues. Use magnification to spot small details.
Get It Graded
Services like PCGS or NGC can officially verify and rate your coin. This is especially important for high-value coins.
Store Properly
Keep your coins in a safe, dry place and avoid cleaning them, as this can reduce their value.

Why Invest?
Rare coins can be a smart investment. Their value tends to grow over time, especially for coins with historical or error-based significance. Many investors view rare coins as a hedge against inflation.
