Many people keep Susan B. Anthony and Sacagawea dollars in jars, drawers, or boxes. Most are common and worth face value or small premiums. However, rare varieties, errors, and authenticated patterns can rise dramatically in value when they have clear provenance and grading.
Why Susan B. Anthony and Sacagawea coins can be valuable
Both series are modern U.S. dollars produced in large numbers. What drives value for an otherwise common coin is scarcity, condition, and collectability. That includes:
- Mint errors (strikes, misplacements, doubled dies).
- Proof and pattern pieces or trial strikes that never entered circulation.
- Unique provenance—coins connected to historical events or famous collections.
- High-grade, professionally graded specimens in flawless condition.
Key terms to understand for Susan B. Anthony and Sacagawea coin value
- Mint mark: Letter indicating where the coin was struck (P, D, S).
- Variety: A recognized difference in design or die among the same date and mint.
- Error: A mistake from the minting process (e.g., off-center, doubled die).
- Grading: Professional evaluation of a coin’s condition (PCGS, NGC).
How to inspect your Susan B. Anthony coin
Check the date and mint mark first, then look closely for obvious errors or unusual features. Use a magnifier and good light.
- Look for doubled elements on the obverse or reverse.
- Check the rim and edge for any irregularities or missing reeds.
- Note heavy die scratches, corrosion, or signs of cleaning—these affect value.
How to inspect your Sacagawea coin
Sacagawea dollars can show edge lettering differences, planchet flaws, or die doubling. Look for:
- Edge lettering or missing edge lettering when applicable.
- Unusual color or luster from composition changes or toning.
- Proof-like surfaces on circulation strikes.
Practical steps if you suspect a high-value coin
If a coin looks unusual, follow a clear process to maximize the chance of a successful authentication and sale.
- Photograph the coin from multiple angles in diffused light.
- Keep the coin protected in a holder; do not clean or polish it.
- Compare the coin to reputable references and auction records online.
- Submit high-value candidates to a recognized grading service (PCGS, NGC).
- Contact a reputable dealer or auction house for consignment if authenticated.
Realistic expectations: can these coins be worth 20 million?
It is extremely rare for modern Susan B. Anthony or Sacagawea dollars to reach truly astronomical prices. Most high-dollar coin auction records involve much older gold or silver rarities.
That said, a unique pattern, an undiscovered trial strike with exceptional provenance, or a once-in-a-century error authenticated and tied to a historic provenance could command very high prices. Think carefully and rely on experts rather than social media claims.
Common valuable things to look for on modern dollar coins
Collectors and experts most often value these features on Susan B. Anthony and Sacagawea dollars:
- Proof or pattern pieces with documentation.
- Major minting errors such as off-center strikes >10% or broadstrikes.
- Doubled dies that are clearly visible on photographs.
- Mules (obverse and reverse mismatches) that are authenticated.
What a professional grading covers
Grading services verify authenticity, assign a condition grade, and often attribute varieties. A single certification can transform an unremarkable coin into an auction-grade lot with global buyer interest.
Case study: How a find becomes sale-ready
A collector discovered an unusual Sacagawea dollar in a roll and noticed a strong doubling on the obverse. They photographed the coin, kept it uncleaned, and submitted it to a grading service. After authentication and a certified attribution, the coin was consigned to a major auction house where serious collectors bid. The grading and auction provenance led to a price far above face value, demonstrating that careful handling and proper authentication matter.
