Identifying a genuine Susan B Anthony dollar proof coin is essential for collectors and investors who want to ensure authenticity and value. Proof coins have distinct features and finishes that set them apart from regular circulation coins, and the Susan B Anthony dollar proof is no exception. This guide provides a detailed, step-by-step approach to help you confidently spot an authentic proof coin, avoid counterfeits, and understand what to look for during inspection.
What You’ll Need
- A well-lit area or a daylight lamp for close inspection
- A magnifying glass or jeweler’s loupe (10x magnification preferred)
- A soft cloth or gloves to handle the coin without damaging it
- Access to reliable reference images or guides of Susan B Anthony proof coins
- A digital scale (optional but useful for weighing the coin)
- A ruler or calipers for measuring dimensions (optional)
Step-by-Step
- Understand the Basics of the Susan B Anthony Proof Dollar
Proof coins are specially minted with polished dies and planchets, resulting in a mirror-like background and frosted raised details. The Susan B Anthony dollar proof coins were minted primarily in 1979, 1980, and 1999. They have a copper-nickel clad composition and weigh about 8.1 grams. - Examine the Coin’s Packaging
Proof coins are typically sold in protective plastic capsules or display cases with official U.S. Mint packaging. If your coin comes loose or in an unofficial holder, proceed cautiously and verify the coin’s authenticity through physical inspection. - Check the Coin’s Weight
Using a digital scale, weigh the coin. A genuine Susan B Anthony proof dollar weighs roughly 8.1 grams (0.286 ounces). Significant deviation could indicate a counterfeit or altered coin. - Inspect the Coin’s Diameter and Thickness
Measure the coin’s diameter; it should be approximately 26.5 millimeters. Thickness should be about 2.0 millimeters. Variations outside standard tolerances can be a red flag. - Look at the Coin’s Finish
The hallmark of a proof coin is its mirror-like background with frosted, sharply defined raised features. Under bright light or a lamp, tilt the coin to observe the contrast between the polished fields and frosted reliefs. A genuine proof will have a deep, reflective surface without blemishes or dull areas. - Examine the Details on the Obverse
The front side features Susan B Anthony’s portrait. Look for crisp, clear lines in her hair, facial features, and clothing. Details should be sharp and free of blurring or flatness typical of circulation strikes. - Inspect the Reverse Design
The reverse depicts an eagle landing on the moon with an olive branch. Verify the clarity of feathers, lettering, and the lunar surface. Proof coins have precise, well-defined details, unlike worn or fake coins. - Check the Edge
The edge of the coin should be reeded (grooved) with consistent spacing and depth. Inconsistencies or smooth edges can indicate a counterfeit or altered coin. - Identify the Mint Mark
Proof Susan B Anthony dollars were minted in Philadelphia (no mint mark) and San Francisco (S mint mark). The mint mark is located on the reverse side, just to the right of the eagle’s wing. Confirm the mint mark matches the coin’s purported origin. - Compare Against Reference Images
Use trusted numismatic websites or official U.S. Mint images to compare your coin’s features. Look for any discrepancies in font, spacing, or design details. - Assess the Coin’s Condition
Proof coins should be free from scratches, dings, or discoloration. Any surface damage can reduce value and may indicate mishandling or a counterfeit attempt. - Consult a Professional if Unsure
If doubts remain after your inspection, consider sending the coin to a reputable grading service like PCGS or NGC for authentication and grading.
Common Mistakes
- Confusing Circulated Coins for Proofs: Circulated Susan B Anthony dollars lack the mirror finish and sharp detail of proofs. Don’t assume a shiny coin is proof.
- Ignoring Mint Marks: Overlooking the mint mark can lead to misidentification, as proof coins often come from specific mints.
- Relying on Weight Alone: While weight is important, some counterfeiters use correct weights but with inferior materials or details.
- Handling the Coin Without Care: Fingerprints and scratches can obscure key features important for verification.
- Using Poor Lighting: Insufficient lighting can hide the proof coin’s characteristic mirror finish, making inspection difficult.
Tips
- Always handle the coin by the edges or wear cotton gloves to prevent oils from damaging the surface.
- Use a magnifying glass or jeweler’s loupe to get a closer look at fine details and surface texture.
- Compare your coin with multiple reference images from trusted sources to spot subtle differences.
- Keep proof coins in protective holders to maintain their condition and value.
- Be wary of deals that seem too good to be true; genuine proof coins usually command a premium.
- Learn the common characteristics of counterfeit Susan B Anthony proofs, such as inconsistent edges or incorrect finishes.
Troubleshooting
If your inspection does not conclusively confirm authenticity, consider the following actions:
- Unclear Details: If details appear blurry or inconsistent, check the lighting and magnification. If still unclear, compare with high-resolution images or seek expert opinion.
- Weight or Size Off: Recalibrate your scale or measurement tools and weigh/measure again. If deviations persist, suspect a counterfeit or altered coin.
- Surface Damage or Tarnish: Avoid cleaning the coin yourself as this can reduce value. Consult a professional for advice on preservation.
- Mint Mark Missing or Suspicious: Research the coin’s year and minting history. Some proof coins have no mint mark (Philadelphia), but a missing mint mark on a coin that should have one is suspicious.
- Still Unsure: Submit the coin to a professional grading service. They can authenticate and grade the coin, providing peace of mind and potentially increasing its market value.
