Why the Number Isn't Everything
Two coins with the exact same grade can look dramatically different — and sell for very different prices. The grade is a summary, but the story involves three critical factors: eye appeal, luster, and strike.
Eye Appeal: The X Factor
Eye appeal is the overall visual impression a coin makes at first glance. Positive factors include original surfaces, attractive toning, even wear, and clean fields. Negative factors include cleaning (unnatural, washed-out appearance), ugly toning, and prominent marks in focal areas.
Cleaned coins receive "Details" grades from PCGS and NGC rather than numeric grades, selling at steep discounts.
Types of Luster
- Cartwheel luster — Rotating bands of light from flow lines. The hallmark of original surfaces.
- Frosty luster — Soft, white, textured surface. Common on Morgan dollars.
- Satiny luster — Smooth, even sheen on copper and bronze coins.
- Prooflike (PL) — Business strikes with mirror-like fields from early die use. Significant premiums.
- Deep Mirror Prooflike (DMPL) — Extreme mirror effect. DMPL Morgan dollars sell for 3–10x normal prices.
Strike Quality
Strike is determined by pressure, die condition, and planchet quality. A fully struck coin shows every detail crisply. Weak strike is not the same as wear — a coin can be MS-65 with a weak strike.
Special Designations That Add Value
- Full Bands (FB) — Mercury dimes with fully separated bands on the fasces. 2–5x premium.
- Full Bell Lines (FBL) — Franklin halves with complete bell lines. Significant premiums.
- Full Steps (FS) — Jefferson nickels with fully defined Monticello steps. Large premiums.
- Full Head (FH) — Standing Liberty quarters with complete head detail.
Practical Buying Advice
- "Buy the coin, not the holder" — Always evaluate the actual coin, not just the label.
- A stunning MS-64 with original toning may be a better purchase than a dull MS-65.
- Avoid "Details" graded coins for investment — steep discounts and hard to resell.
- See coins in person at coin shows and work with trusted dealers.

Frequently Asked Questions
What is eye appeal in coin grading?
Eye appeal is the overall visual impression a coin makes. It encompasses original surfaces, attractive toning, even wear, and clean fields. Two coins with the same grade can have very different eye appeal and sell for different prices.
What is prooflike on a coin?
Prooflike (PL) describes a business-strike coin with mirror-like fields from early die use. Deep Mirror Prooflike (DMPL) shows even stronger mirror surfaces. Both carry significant premiums, especially for Morgan dollars.
What does Full Bands mean on a Mercury dime?
Full Bands (FB) means the horizontal bands on the fasces reverse are fully separated, indicating a strong strike. FB Mercury dimes sell for 2–5x non-FB examples.
