1916-D Mercury Dime
The 1916-D Mercury Dime is one of the most desired coins among collectors. It was minted in Denver, and only 264,000 were produced, making it the rarest of all Mercury dimes.
Why is it valuable?
- It was one of the first Mercury dimes ever made
- Features a Winged Liberty Head, often mistaken for the Roman god Mercury
- Limited mintage, making it extremely hard to find in good condition
A high-grade 1916-D Mercury Dime can sell for well over $100,000. In fact, one graded MS-67 by the Professional Coin Grading Service (PCGS) sold for an incredible $207,000 at auction.
If you own a well-preserved 1916-D Mercury Dime, it could be a life-changing discovery.
1975 No-S Roosevelt Dime Proof
The 1975 No-S Roosevelt Dime Proof is a modern rarity that has stunned collectors. Normally, proof dimes minted in San Francisco have an “S” mintmark. However, a minting error led to a few 1975 proof dimes being produced without the “S” mintmark.
Why is it valuable?
- Only two known examples exist
- Found in original proof sets, making them even rarer
- One of the rarest modern U.S. coins
Because of its extreme rarity, one of these dimes sold for $350,000 at auction. If you find a 1975 No-S Roosevelt Dime Proof, you could be holding one of the rarest and most valuable dimes in history.
1776–1976 Bicentennial Quarter
The Bicentennial Quarter was released to celebrate the 200th anniversary of American independence. While millions of these quarters were made, some rare error coins are worth thousands of dollars.
Why is it valuable?
- Some quarters feature a doubled die error (DDO or DDR) on either the front or back
- These errors occur when the design is struck twice slightly off-center, creating a doubling effect
- Collectors prize these error coins due to their historical significance and scarcity
Depending on the severity of the doubling and coin condition, these Bicentennial quarters can sell for $2,000 to $20,000.
