The Mercury dime, designed by Adolph A. Weinman, is widely regarded as one of the most beautiful US coins ever produced. Let's examine its key design elements:

Factors Affecting the Value of a 1942 Mercury Dime
Several key factors determine a 1942 Mercury dime's worth:
- Mint mark and mintage
- Condition (grade)
- Full Bands designation
- Errors and varieties
- Silver content
Let's explore each of these in detail.
Mint Marks and Mintages
In 1942, Mercury dimes were produced at three different mints:
| Mint Location | Mint Mark | Mintage |
|---|---|---|
| Philadelphia | None | 205,410,000 |
| Denver | D | 60,740,000 |
| San Francisco | S | 49,300,000 |
The mint mark, when present, is located on the reverse near the bottom of the coin.
Grading and Condition
The condition of a coin significantly impacts its value. The Sheldon Scale, ranging from Poor (P-1) to Perfect Mint State (MS-70), is used for grading. For 1942 Mercury dimes, key grade points include:
| Grade | Abbreviation | Description |
|---|---|---|
| Good | G-4 | Major design elements visible but heavily worn |
| Very Good | VG-8 | Design clear but lacking in finer details |
| Fine | F-12 | All major features clear, some minor detail visible |
| Very Fine | VF-20 | Most minor details visible, moderate wear |
| Extremely Fine | EF-40 | Light wear on high points, all details sharp |
| About Uncirculated | AU-50 to AU-58 | Slight wear on highest points, some luster remaining |
| Mint State | MS-60 to MS-70 | No wear, ranging from many marks to nearly perfect |
Full Bands Designation
The "Full Bands" (FB) designation is crucial for Mercury dimes. It refers to the complete separation of the horizontal bands on the fasces on the reverse. Full Bands examples are rarer and command higher premiums.
To qualify for Full Bands:
- Central bands must be fully split
- Bands must have sharp, clear definition
- No significant wear or flatness in the band area
Errors and Varieties
The 1942 Mercury dime has some notable errors and varieties that can dramatically increase its value:
-
1942/1 Overdate:
- Found on both Philadelphia and Denver issues
- A 1941 die was re-engraved to 1942
- Easily visible "1" underneath the "2" in the date
-
Doubled Die Obverse:
- Shows doubling in the date or other design elements
- Most noticeable in "LIBERTY" or date area
-
Re-punched Mint Mark:
- Particularly on Denver coins
- "D" may appear to be stamped twice
Silver Content
As a pre-1965 dime, the 1942 Mercury dime is composed of 90% silver and 10% copper. This gives it an inherent melt value based on the current silver price.
| Silver Price | Melt Value |
|---|---|
| $20/oz | $1.44 |
| $25/oz | $1.80 |
| $30/oz | $2.16 |
Note: Melt value is typically only relevant for heavily worn or damaged coins, as collectible value usually exceeds melt value.
