1916-D Mercury Dime
The 1916-D Mercury Dime is a crown jewel for collectors. With only 264,000 coins minted in Denver, it is the rarest of the Mercury Dime series. Its historical significance as one of the first Mercury dimes ever produced makes it highly desirable.
The coin features a Winged Liberty Head design, often mistaken for the Roman god Mercury. This iconic imagery, paired with its rarity, drives its immense value. A 1916-D Mercury Dime graded MS-67 by the Professional Coin Grading Service (PCGS) sold for an astounding $207,000.
If you own one in exceptional condition, it could significantly boost your net worth.
| Coin | Mint Year | Mint Location | Known Quantity | Value |
|---|---|---|---|---|
| 1916-D Mercury Dime | 1916 | Denver | 264,000 | $207,000 |
1975 No-S Roosevelt Dime Proof
The 1975 No-S Roosevelt Dime Proof is a modern rarity born of a minting error. Most proof dimes minted in San Francisco carry an “S” mintmark, but a few dimes from 1975 were struck without this mark due to an oversight.
With only two known examples, this dime is one of the rarest ever minted. Initially discovered in proof sets, these dimes have achieved legendary status among collectors. One such coin recently sold at auction for $350,000.
If you come across a 1975 proof set missing the “S” mintmark, you could be holding a fortune.
| Coin | Mint Year | Special Feature | Known Quantity | Value |
|---|---|---|---|---|
| 1975 No-S Roosevelt Dime | 1975 | Missing “S” Mark | 2 | $350,000 |
1776–1976 Bicentennial Quarter
The 1776–1976 Bicentennial Quarter was created to celebrate America’s 200th anniversary. While millions of these quarters were minted, a select few with unique errors, such as doubled dies on the obverse (front) or reverse (back), are incredibly valuable.
These doubled die errors occur when the coin’s design is struck twice slightly off-center, creating a doubled image. Coins with such errors in high grades can fetch between $2,000 and $20,000, depending on the clarity of the doubling and the condition of the coin.
The Bicentennial Quarter’s historical significance and the rarity of these error coins make them a prized addition to any collection.
| Coin | Mint Year | Special Feature | Value Range |
|---|---|---|---|
| 1776–1976 Bicentennial Quarter | 1976 | Doubled Die (DDO/DDR) | $2,000–$20,000 |
