The Susan B. Anthony dollar is a common modern U.S. coin, but a few very rare examples can be extremely valuable. This guide explains how collectors spot the varieties and errors that drive prices into six figures, and what steps to take if you think you own one.
Why a Susan B. Anthony dollar can be worth 880K
Most Susan B. Anthony (SBA) dollars sell for face value up to modest collector premiums. A very small number of SBA dollars, however, have unique die varieties or major minting errors and exceptional condition that make them rare.
High auction prices combine three things: extreme rarity, a dramatic error or clearly identifiable variety, and top certified grade. Provenance or a documented discovery history can also push prices much higher.
Key identifiers for high-value Susan B. Anthony dollars
When screening coins, prioritize clear, objective signs that indicate a rare variety or error. Look for:
- Unusual die doubling on the obverse or reverse (doubled die).
- Major mint errors such as off-center strikes, broadstrikes, or double strikes.
- Repunched mint marks (RPM) or misplaced mint marks that are clearly visible.
- Planchet issues like large clipped planchets or severe lamination defects.
- Exceptional preservation: full luster and Mint State grading (MS) or PR (proof) grades near 69–70.
How to spot a Susan B. Anthony dollar worth 880K
Follow a step-by-step check routine to separate ordinary examples from candidates worth professional study.
1. Check the date and mint mark
Most SBA dollars were struck beginning in 1979. Note the date and look for mint marks (D, S, or no mint mark for Philadelphia strikes). Some rare varieties are tied to specific years and mint marks.
2. Examine the coin under magnification
Use a 5x–10x loupe or macro camera to inspect details. Look for doubling on Liberty’s profile, lettering, or the eagle on the reverse. Doubling that appears on the devices (letters or portrait) rather than just on the rims can indicate a doubled-die variety.
3. Identify major errors
Major errors command top prices. Check for:
- Off-center strikes (significant displacement of the design).
- Double strikes where the entire design appears twice.
- Severe planchet defects: missing metal, large clips, or lamination failures.
4. Assess condition and luster
Condition is crucial. Even rare errors have limited value if the coin is heavily worn. Mint State (MS) coins or high-grade proofs with full original luster attract the biggest bids.
5. Compare to known reference examples
Use reputable references—specialty hobby guides, auction archives, and professional numismatic publications—to compare diagnostic photos and descriptions. If a coin matches a documented rare variety, it may warrant grading and further research.
Some Susan B. Anthony dollars that achieved six-figure auction prices were unique error pieces or extremely rare proof varieties certified at the highest grades.
Authentication and grading
If you find a candidate, do not clean or alter the coin. Cleaning will severely reduce value and can invalidate potential sales. Pack the coin safely and seek professional grading.
Submit the coin to major grading services such as PCGS or NGC. Grading will provide an expert opinion on authenticity, grade, and whether the piece matches known varieties.
Provenance and documentation
Document how and where you found the coin. Auction houses and collectors pay attention to provenance. If the coin has prior certification, include that paperwork when you seek an updated evaluation.
Case study: a high-value Susan B. Anthony candidate
A collector discovered a Susan B. Anthony dollar in a dealer lot that showed dramatic doubling on the obverse and a matching reverse error. After careful comparison to reference photos and submitting images to an experienced numismatist, the piece was encapsulated and sent to a grading service.
At auction, the certified error example drew international bidding due to its rarity and superb preservation. The sale illustrates the path from discovery to certification to auction realization for high-value modern coins.
Final checklist before you act
- Do not clean the coin; preserve original surfaces.
- Photograph the coin with a macro lens in good light.
- Compare the coin to trusted references and auction archives.
- Seek opinions from experienced numismatists or local coin clubs.
- Submit to a professional grading service if the coin looks exceptional.
Finding a Susan B. Anthony dollar that could reach prices like $880K is rare, but careful inspection and correct procedure will maximize your chance of recognizing and realizing the coin’s value. If your coin shows any of the major error characteristics described here, document everything and get expert help.
