Collectors and casual finders often ask whether a Mercury or a Roosevelt dime is worth more. The short answer is: it depends. Value comes from date, mintmark, condition, and rarity, not just the design name.
Key differences: Mercury vs Roosevelt dimes
Mercury dimes were struck from 1916 to 1945, and Roosevelt dimes began in 1946 and continue today. Both series used 90% silver from their starts until 1964 for Roosevelt dimes, and all Mercury dimes are 90% silver.
Knowing these production dates helps set a baseline: most pre-1965 dimes have intrinsic silver value, while later Roosevelt dimes typically do not.
Silver content and melt value
Both Mercury (1916–1945) and Roosevelt (1946–1964) dimes contain 90% silver. That metal content creates a minimum floor value tied to the current silver price.
When silver prices rise, even common circulated dimes from these years will trade above face value. However, collector value can far exceed melt value for key dates or high grades.
Date, mintmark, and rarity
Date and mintmark are the next most important factors. A common Mercury or Roosevelt date in worn condition might only be worth its silver content.
Key Mercury dates (for example, the 1916-D) are much rarer and often collectible at a premium. Some Roosevelt dates and mint errors are also rare, but many Roosevelt dimes exist in large numbers.
How collectors decide which dime is worth more
Collectors and dealers compare a few standard factors when pricing coins. None of these alone determines value—it’s the combination that matters.
- Date and mintmark: Key dates are scarce and usually worth more.
- Condition (grade): A high-grade coin can be exponentially more valuable than a worn one.
- Errors and varieties: Striking errors, doubled dies, and mint varieties can add value.
- Silver content: Sets a minimum value for pre-1965 dimes.
- Demand: Popular series or dates attract stronger bidding in auctions.
Condition and professional grading
Condition is measured on the 70-point Sheldon scale. An MS (Mint State) 65 Mercury dime is dramatically more valuable than an XF (Extremely Fine) example.
Getting a rare coin professionally graded by NGC or PCGS can confirm quality and help you achieve fair sale prices. Grading is especially worthwhile for key dates or suspected high-grade pieces.
Key dates and examples to watch in Mercury vs Roosevelt dimes
Some dates are famous among collectors. For Mercury dimes, the 1916-D is a well-known key date because of its low mintage. For Roosevelt dimes, 1949-S and certain proof and error varieties attract attention.
Remember that specific auction results vary by grade. Price guides (PCGS, NGC, and major auction houses) list ranges that help set realistic expectations.
Mercury dimes are not actually a depiction of Mercury. The figure is Liberty wearing a winged cap, symbolizing freedom of thought.
Errors and varieties that increase value
Errors such as double dies, repunched mintmarks, and off-center strikes can add significant value when verified. Both Mercury and Roosevelt series have collectible errors.
Make sure suspected error coins are inspected by an experienced dealer or submitted for grading. Many apparent errors are common or caused by post-mint damage and will not be worth extra.
How to check if your dime is valuable
Follow these practical steps to assess a dime’s potential value:
- Examine the date and mintmark under magnification.
- Compare wear to printed grade guides or online images.
- Look for obvious errors or unusual devices.
- Check current silver prices to estimate melt value for pre-1965 dimes.
- Consult price guides or recent auction results for similar dates and grades.
How to sell or get a coin appraised
If you suspect a dime is worth more than melt value, start by asking a reputable local dealer or submitting clear photos to online coin forums. For high-value coins, professional grading is a next step.
Auction houses and reputable dealer networks typically return higher prices than quick buys from pawn shops. Always document sales and get multiple opinions for significant items.
Real-world case study
Case study: A collector examined two dimes found in an estate lot — one Mercury and one Roosevelt. Both looked worn, but the Mercury had a clear 1916-D mark. After research and a dealer consultation, the collector learned the Mercury was a key-date candidate and pursued grading. The Roosevelt dime was common and sold for near melt value, while the authenticated 1916-D Mercury qualified for auction and fetched a multiple of the silver value due to rarity and grade.
This example shows the practical step: check date and mintmark first, then decide whether expert grading or sale at auction makes sense.
Final advice: Which small coin is worth more?
There is no universal answer. A typical worn Mercury dime and a typical worn Roosevelt dime of the same silver era will be worth similar amounts based on silver. The coin worth more is usually the one with a rarer date, better condition, or collectible error.
When in doubt, document the coin, consult price guides and experienced dealers, and consider grading for any suspected high-value pieces. That approach will tell you whether Mercury or Roosevelt dimes in your possession are the better financial find.
