Do you have old coins lying around in your drawer or piggy bank? Some Mercury dimes and Lincoln pennies look ordinary but can be hidden treasures worth a lot of money. These small U.S. coins from the early 1900s are popular with collectors because of their history, low numbers made, special mint marks, and minting errors. In 2026, certain rare versions still fetch high prices at auctions—sometimes thousands or even millions of dollars!
Coin collecting (called numismatics) is fun and can be profitable. Many people find valuable coins in old jars, family collections, or even pocket change. Let’s explore why these coins are special and look at some of the rarest ones.
What Are Mercury Dimes?
Mercury dimes were made from 1916 to 1945. (Note: The lady on the front is Liberty with wings on her cap, not the planet Mercury—that’s why it’s officially called the Winged Liberty Head dime.)
- Front side: Shows Liberty with a winged cap (symbol for freedom of thought).
- Back side: Has a bundle of sticks (fasces for strength) and an olive branch (for peace).
- Material: 90% silver, so they have some melt value too.
- Why some are rare: Low numbers produced in certain years, special mint locations (like “D” for Denver or “S” for San Francisco), and errors.
These coins were used a lot in daily life, so finding one in perfect shape is hard and makes it very valuable.
What Are Lincoln Pennies (Wheat Cents)?
Lincoln pennies started in 1909 to honor Abraham Lincoln’s 100th birthday. The “Wheat” version (with wheat stalks on the back) ran until 1958.
- Front side: Abraham Lincoln’s portrait.
- Back side: Two wheat ears (that’s why called Wheat pennies).
- Material: Mostly copper (except some wartime steel versions).
- Why some are rare: Very low production in early years, famous initials like “VDB,” and big errors like doubled words or wrong metal.
Billions of pennies were made overall, but specific rare ones stand out.
Key Factors That Make These Coins Valuable
Several things decide if a coin is worth a lot:
- Low mintage (few made).
- Mint mark (small letter showing where made: no letter = Philadelphia, D = Denver, S = San Francisco).
- Condition (graded on a scale; MS65+ means almost perfect, no wear).
- Errors (mistakes like doubled designs, off-center strikes, or wrong planchet/metal).
- Demand from collectors and investors.
High-grade (top condition) rare coins can sell for much more than worn ones.
