Mercury Dime grading, in brief
Mercury dimes (1916–1945) are graded 1–70 on the Sheldon scale. Grade depends on wear to Liberty's hair and the fasces on the reverse, and — for premium Mint State coins — whether the two horizontal bands on the fasces are fully separated ('Full Bands' / FB), a designation that can multiply value.
Full Bands (FB) is the value multiplier
On the reverse, the fasces has horizontal bands across its center. When the central pair of bands is fully rounded and completely separated by a visible split, the coin earns the 'Full Bands' (FB) designation — which can multiply the value of a Mint State Mercury dime. Weak strikes blur these bands even on otherwise high-grade coins.
What graders look at
Hair along the face
Liberty's hair detail above the ear and along the face wears first on the obverse.
Fasces & diagonal bands
The diagonal bands wrapping the fasces show wear before the central horizontal bands.
Central horizontal bands (FB)
Full separation = Full Bands. The single biggest value driver in Mint State.
Rims & fields
Check for nicks and contact marks in the open fields for high MS grades.

Mercury Dime grading FAQ
How do I grade a Mercury dime?
Check hair detail near Liberty's face and the fasces on the reverse for wear, then — for Mint State coins — whether the central horizontal bands are fully separated (Full Bands). Compare against a grade chart.
What are Full Bands on a Mercury dime?
Full Bands (FB) means the central pair of horizontal bands on the reverse fasces is fully rounded and completely split. It's a premium designation that can significantly increase value.
Which Mercury dimes are valuable?
The 1916-D is the key date and valuable in all grades. The 1921, 1921-D, and 1942/1 overdates also carry strong premiums.
Is a 1916-D Mercury dime worth grading?
Almost always yes — it's the series key date and grading provides authentication (counterfeits and altered dates exist), plus a value premium.
How much is a Mercury dime worth?
It depends entirely on date and grade (common silver dimes are worth a few dollars in melt; key dates and Full Bands gems reach thousands). We estimate the grade; check a price guide like PCGS or NGC for current values.
