Rare coin collection is not just a hobby; It can also be a profitable investment. Today, there are some coins in circulation that deserve a small fortune, such as three rare dims and a Bicentennial Quarter costs $170 million. But how do you know which coins deserve so much money? Whether you are an experienced number or a hobby collector, this guide will help you identify these rare finds, know your value and ensure that you do not miss a burial tax in your pocket.
$170M Bicentennial Quarter
The 1976 Bicentennial Quarter was produced to commemorate America’s 200th year. Although most of these quarters are ordinary, there is one rare variant that sells for $170 million because of its peculiar minting flaw, metal content, and mint condition.
How to Tell if You Have a Valuable Bicentennial Quarter
To check if you have a valuable Bicentennial Quarter, check for these distinctive characteristics:
- Double Die Obverse (DDO): If the lettering on the obverse of the coin seems doubled, it may be a rare mistake.
- No Mint Mark: Some of the rare ones have no mint mark, which means a special release.
- Silver Conten:t Most Bicentennial Quarters were of copper-nickel, with rare ones produced in 40% silver or even 90% silver.
- Mint-State Condition: In mint condition (MS-67 or above), coins are valued the highest.
- Proof Issues with Deep Cameo Contrast: Extremely detailed and mirror-like surface.

3 Rare Dimes Worth Thousands
1. 1894-S Barber Dime – Worth Over $2 Million

Perhaps one of the most sought-after dimes in U.S. history, the 1894-S Barber Dime is a collector’s holy grail.
How to Identify It:
- Depicts Lady Liberty donning a Phrygian cap adorned with a laurel wreath.
- Features the “S” mint mark below the wreath to show it was minted in San Francisco.
- Only 24 were ever produced, and only 9 are known to survive today.
2. 1916-D Mercury Dime – Worth $25,000+
1916-D Mercury Dime is very coveted because of its very low mintage figures.
Key Identifiers:
- Has Winged Liberty Head on the front.
- Has tiny “D” mint mark at the back (Denver Mint).
- Only produced 264,000, so is extremely scarce.
3. 1942/41 Mercury Dime – Valued At More Than $30,000

It bears a striking overdate error, where the date for 1942 was punched over a die for 1941 by mistake.
How to Identify It
- Notice the date closely; you’ll be able to see a light “1” in the back of the “2.”
- Found in both Philadelphia (no mint mark) and Denver (“D” mint mark) mint marks.
- Well-graded specimens can sell for $30,000 or more in auctions.
How to Check If You Have a Rare Coin?
- Check the Date and Mint Mark: Always look at the date and mint mark. Certain mints made fewer coins, so they are worth more.
- Check for Minting Errors: Coins with errors such as double dies, off-center strikes, or overdates are worth much more.
- Check the Metal Content: Coins with silver or gold content in them are worth more. Test with a magnet—silver and gold won’t stick.
- Evaluate the Coin’s Condition:
Good (G) – Worn, nearly illegible details
Fine (F) – Partially visible details, moderate wear
Uncirculated (MS-60 or better) – Sharp details, no wear - Obtain a Professional Evaluation: If you believe your coin is scarce, have it professionally graded by PCGS or NGC to determine an accurate value.
Final Thought
The search for rare coins is exciting, and a humble dime or quarter might make your life.

Begin looking through your pocket change—you could be sitting on a treasure trove!
