How to grade a Mercury Dime — and every coin like it.

The Mercury Dime is the standard teaching coin for the Sheldon grading scale. Once you can grade a Mercury, you can grade nearly any pre-1965 US silver coin — the wear pattern follows the same playbook.

The teaching coin

1916–1945 · 90% silver · Adolph Weinman, designer · officially the "Winged Liberty Head" dime — the cap with wings represents liberty of thought, not the Roman god Mercury. Click either photo to view it at full size.

The six grades you'll actually see

The Sheldon scale runs from 1 (Poor) to 70 (Perfect Mint State). In the wild, you'll meet six bands. Each one is defined by what's missing — every grade is a wear-down of the one above.

Good · G-4

The whole design is visible — and that's it.

You can identify the coin and read the date. Liberty's profile is a flat outline. The wings on the cap have lost their feather detail entirely. The reverse fasces (the Roman bundle of rods) shows as a single smooth bundle with no horizontal band detail. The rim is starting to merge into the field on at least one side.

Quick check: if the date is readable and the coin looks like a Mercury Dime, but the wings and fasces bands are smooth — that's Good.

Fine · F-12

Major features distinct, fine details worn smooth.

Liberty's hair shows broad strands but no individual lines. The wing has visible separation between the cap and the feathers, but the feathers themselves are merged. The reverse fasces shows the outline of the central horizontal bands but they're not separated. The rim is full and clear all the way around.

Quick check: hair is clearly hair (not a smooth helmet), but you can't count individual strands.

Very Fine · VF-20 to VF-30

Most detail intact; clear wear only on the high points.

You can see the major hair strands. The wing feathers are individually defined except at the very tips. On the reverse, the horizontal central bands of the fasces are visible as separate lines but the central groove between them isn't crisp.

Quick check: if you can see hair strands AND the central fasces bands as distinct lines (even if soft) — VF.

Extremely Fine · XF-40 to XF-45

All design elements sharp; only the highest points show wear.

Liberty's hair is fully detailed. The wing feathers are fully separated to the tips. On the reverse, the fasces bands are sharp and you can see the diagonal binding cords. Only the very top of the wing and Liberty's brow show light flatness from circulation.

Quick check: if you have to tilt the coin in the light to find any wear, you're at XF.

About Uncirculated · AU-50 to AU-58

Looks new on first glance — minimal wear on the highest point.

From any normal viewing distance the coin appears uncirculated. Under magnification, you'll see a faint friction or rub on the very highest point of the wing or hair — a slightly different luster from the surrounding fields. Underlying mint luster is still mostly present in the protected areas.

Quick check: the coin shimmers like new but a 5x loupe reveals a soft "rubbed" patch on the wing. AU-58 is what most uncirculated rolls actually grade at.

Mint State · MS-60 to MS-65

No circulation wear. Differences are about marks and luster.

By definition Mint State coins have zero wear. The grading distinction comes down to bag marks, contact dings, the strength of the original mint luster, and the strike quality. MS-60 has heavy bag marks and dull luster; MS-63 is what most "uncirculated" coins grade out at; MS-65 is gem-quality with minimal marks and full booming luster. Above MS-65 you're in pricing territory only matters to investors.

Quick check: no flatness anywhere; the coin glows when you tilt it under a single light source.

The "Full Bands" designation — Mercury's signature

On the reverse fasces, two horizontal bands wrap the central section. A coin where both bands show a complete, unbroken split line down the middle earns the Full Bands (FB) designation — abbreviated MS-65FB, MS-66FB, etc. Most mint state Mercury Dimes do NOT have Full Bands because the dies wore down quickly during striking, and even fresh-from-the-mint coins often had merged bands.

FB coins can be 5–20× the value of a non-FB coin at the same numeric grade. If you're sorting a roll, the fasces bands are the first thing to look at — under a 5x loupe, in good light. This is the single most valuable grading skill for this series.
