What is a Mercury Dime?
The Mercury dime is a ten-cent coin minted in the United States from 1916 to 1945. It features a left-facing portrait of Liberty wearing a winged cap, symbolizing freedom of thought. Although often mistaken for the Roman god Mercury, the design represents Lady Liberty.
The History of Mercury Dimes
The Mercury dime was introduced as part of an effort to beautify U.S. coinage in the early 20th century. Designed by Adolph A. Weinman, the coin replaced the Barber dime, which had been in circulation since 1892. Weinman was also responsible for designing the Walking Liberty Half Dollar, another beloved American coin. The Mercury dime’s design was considered revolutionary at the time, incorporating classical influences while reflecting the modern spirit of the early 1900s.
The coin was produced in three mints:
- Philadelphia (No mint mark)
- Denver (D mint mark)
- San Francisco (S mint mark)
Why Are Mercury Dimes Valuable?
- Historical Significance – Part of early 20th-century U.S. coinage, making them highly collectible.
- Silver Content – Composed of 90% silver, each dime has intrinsic value even if it’s not rare.
- Key Date Rarity – Certain years and mint marks have very low production numbers, making them scarce.
- Mint Errors and Full Bands (FB) – Coins with overdates or Full Bands on the reverse can fetch premium prices.
How to Identify a Valuable Mercury Dime
1. Check the Date and Mint Mark
Some Mercury dimes are more valuable than others based on their mint year and location. The mint mark is located on the reverse side, near the bottom left of the fasces (bundle of sticks symbolizing unity).
Key Dates and Values:
- 1916-D – Most valuable! Only 264,000 minted, making it a rare key date. Value: $1,000 – $207,000.
- 1921 & 1921-D – Low mintage years. Value: $60 – $12,000+.
- 1942/41 Overdate – A mint error where the 1941 date appears under 1942. Value: $500 – $120,000.
2. Look for the Full Bands (FB) Designation
The term Full Bands (FB) refers to the strong strike of the reverse design, where the bands on the fasces are fully separated. Coins with Full Bands are far more valuable.
- Example: A regular 1916-D dime in XF40 grade is worth $3,000, but the same coin with Full Bands in MS67 can be worth over $200,000!
3. Condition and Grading Matter
Coin value depends heavily on its condition. Professional grading companies such as PCGS and NGC use a scale from 1 (Poor) to 70 (Perfect Mint State). Higher grades bring higher prices.
Example Mercury Dime Values by Grade:
| Year | Good (G4) | Fine (F12) | Uncirculated (MS63) | Full Bands (MS67 FB) |
| 1916-D | $1,000 | $4,500 | $20,000 | $207,000 |
| 1921 | $60 | $250 | $5,000 | $20,000 |
| 1942/41 | $500 | $2,500 | $15,000 | $120,000 |
