Coin collecting isn’t just a fun hobby—it’s like going on a treasure hunt! Imagine finding a rare coin in your collection that’s worth a fortune. Some coins are so unique and valuable that they can make you a millionaire overnight. Let’s take a closer look at three coins every collector dreams of owning: the 1916-D Mercury Dime, the 1975 Roosevelt Dime Proof with no “S,” and the Bicentennial Quarter with a doubled die error.

Mercury
One of the most desirable coins for collectors is the 1916-D Mercury Dime. What makes this coin so special? It’s rare—only 264,000 were ever minted in Denver, making it the rarest Mercury Dime. This coin is especially important because it was among the first Mercury Dimes ever produced.
The design features a Winged Liberty Head, which is often mistaken for the Roman god Mercury. That unique look adds to its charm. Coins in excellent condition can fetch unbelievable prices. For example, a 1916-D Mercury Dime graded MS-67 by the Professional Coin Grading Service (PCGS) sold for an impressive $207,000. If you have one in mint condition, it could significantly boost your finances.
| Coin | Mint Year | Mintage | Estimated Value |
|---|---|---|---|
| 1916-D Mercury Dime | 1916 | 264,000 | $100,000–$207,000+ |
Roosevelt
Another incredible rarity is the 1975 No-S Roosevelt Dime Proof. Typically, proof coins minted in San Francisco have an “S” mintmark. But in 1975, a mistake resulted in a batch of proof dimes without the “S” mintmark.
Only two examples of this coin are known to exist, and they were initially observed in proof sets. This rarity has made these dimes highly valuable. One of these coins sold for $350,000 at an auction. If you’re lucky enough to find one in your collection, it’s like hitting the jackpot.
| Coin | Mint Year | Known Examples | Estimated Value |
|---|---|---|---|
| 1975 No-S Roosevelt Dime Proof | 1975 | 2 | $350,000 |
Bicentennial
Finally, we have the 1776–1976 Bicentennial Quarter, a coin minted to celebrate the United States’ 200th anniversary. While millions of these coins were produced, a few feature an error that makes them highly collectible. These errors are known as doubled die obverses (DDO) or doubled die reverses (DDR).
A doubled die error occurs when the coin’s design is struck twice, slightly off-center, creating a doubled image. Depending on the severity of the doubling and the condition of the coin, these quarters can sell for $2,000 to $20,000 or even more.
| Coin | Mint Year | Error | Estimated Value |
|---|---|---|---|
| 1776–1976 Bicentennial Quarter | 1976 | Doubled Die | $2,000–$20,000 |
Rare coins like these are not just valuable—they’re a piece of history you can hold in your hand. From the Mercury Dime’s elegant design to the Bicentennial Quarter’s patriotic significance, each coin tells a fascinating story.
