1981-S Susan B. Anthony Dollar Type 2 FS-501

Documented Fact FS-501 is the 1981-S Type 2 proof Susan B. Anthony dollar, distinguished from Type 1 by the clearer final S mintmark punch. ^{[1] [2]}

Quick Hunt

1. Confirm the coin is a 1981-S proof, not a circulation strike.
2. Inspect the S mintmark above Anthony’s right shoulder.
3. Look for the clear, well-defined Type 2 S rather than the more filled Type 1 form.
4. Compare the complete mintmark silhouette with certified FS-501 examples.

Diagnostic illustration — not a photograph.

Primary Diagnostic

Type attribution depends on the mintmark punch, not cameo strength or grade. The Type 2 S should retain clear internal definition and the certified outline; glare or frost must not be mistaken for shape.

What It Is Not

A Type 1 proof has the earlier, more filled-looking S. A damaged or polished mintmark cannot be promoted to Type 2 from one apparently open area.

Authentication Caution

Use stable magnification and several lighting angles. Match the complete diagnostic relationship to certified examples, do not clean or alter the coin, and obtain professional authentication before paying a substantial premium.
