The 30-second version
A circulated common-date Mercury dime is worth its silver content — roughly $1.80–$3 at current spot prices. Uncirculated common dates run $8–$25. The series’ key dates and Full Bands specimens reach $1,000–$50,000+.
Why it’s called “Mercury”
Adolph A. Weinman’s 1916 design shows Liberty wearing a winged Phrygian cap, symbolizing freedom of thought. Collectors quickly nicknamed it the “Mercury” dime after the Roman messenger god, and the name stuck.
Mint marks
The mint mark is on the reverse, lower-left of the fasces:
- (blank) — Philadelphia.
- D — Denver.
- S — San Francisco.
Key dates to know
- 1916-D— the series key. Just 264,000 minted. Even worn examples bring $1,000–$2,500; problem-free Mint State specimens reach $15,000–$50,000+. Counterfeits are common — have one authenticated before celebrating.
- 1942/1 overdate (Philadelphia) and 1942/1-D overdate— the “2” was punched over a “1” on a small portion of dies. Circulated: $500–$1,500. Mint state: $3,000–$15,000.
- 1921 and 1921-D— semi-keys; not as rare as the 1916-D, but tough in higher grades. Circulated: $50–$150. Mint state: $300–$2,000+.
Full Bands (FB) — the premium designation
The reverse fasces (the bundle of rods) has two horizontal bands wrapping around the middle. On a well-struck coin those bands show full, distinct separation; on most coins they merge. PCGS/NGC mark qualifying coins FB. The premium can be large:
- An MS-65 common-date Mercury runs roughly $30–$50 without FB; the same coin FB runs $80–$200.
- For tougher dates the FB premium can be 5× or 10× the non-FB value.
If you have what looks like a sharp, original Mercury dime, it’s worth a closer look before assuming it’s worth melt.
Common dates: pricing
- Worn (G–VG): silver melt — about $1.80–$2.50.
- Fine to Extremely Fine (F–XF): $2.50–$5.
- About Uncirculated (AU): $5–$10.
- Mint State 60–63: $8–$20.
- Mint State 64–65: $20–$50; FB examples 2–4×.
- Mint State 66–67+ FB: $100–$1,000+ depending on date.
What to do next
- Sort by date and mint mark; do not clean. Pull aside any 1916-D and any 1942 with a visible “1” under the “2”.
- Examine the reverse fasces under good light — if you see full, distinct band separation, the coin may qualify for the FB premium.
- Photograph notable coins, obverse and reverse.
- Send photos to a numismatist for a free appraisal.
Common questions
How much silver is in a Mercury dime?
Each Mercury dime contains 0.07234 troy oz of pure silver (2.25g of silver in a 2.5g coin — the rest is copper). A $1 face-value roll of 10 contains 0.7234 oz.
Is the 1942/1 overdate visible without a magnifier?
On well-preserved coins, the upper portion of the '1' is visible inside the loop of the '2' to the naked eye. On worn coins, you'll need 5x–10x magnification. Both 1942/1 and 1942/1-D varieties exist.
What if my 1916-D doesn't look quite right?
Many circulated 1916-D specimens have been altered from genuine 1916 (Philadelphia) coins by adding a fake 'D'. Have any suspected 1916-D authenticated by PCGS, NGC, or a working numismatist before celebrating.
