Why Are Some Coins Worth Millions?
Certain coins sell for astronomical prices due to rarity, mint errors, historical significance, and condition. Coins that were part of a limited mintage, struck with an error, or preserved in pristine condition often fetch far more than their face value.
Record-Breaking Sales
Here are some of the most valuable dimes and quarters ever sold:
| Coin Type | Sale Price | Why It’s Rare |
|---|---|---|
| 1894-S Barber Dime | $2 million+ | Only 24 minted, 9 known to exist |
| 1976-S Silver Proof Quarter | $20,000+ | Collector’s version struck in silver |
| 1970-S Proof Quarter | $300,000+ | Error coin struck on a 1941 Canadian quarter |
What Makes a Coin Valuable?
If you’re wondering what determines a coin’s value, consider these key factors:
- Low Mintage: The fewer coins produced, the rarer (and more valuable) they are.
- Mint Errors: Misprints, off-center strikes, and wrong-planchet errors are highly sought after by collectors.
- Condition: Coins graded MS-65 or higher by professional grading services (PCGS or NGC) fetch premium prices.
- Historical Rarity: Coins from significant years or with unique historical backstories attract more interest.
