Identifying a DCAM (Deep Cameo) proof Susan B Anthony dollar coin can be rewarding for coin collectors, as these coins are prized for their sharp contrast and mirror-like finish. Knowing how to distinguish a genuine DCAM proof coin from other varieties helps ensure accurate valuation and adds confidence to your collection. This guide walks you through the process step-by-step, including what to look for and common pitfalls to avoid.
What You’ll Need
- A well-lit area with natural or bright white light
- A magnifying glass or jeweler’s loupe (10x magnification recommended)
- A clean, soft cloth or gloves to handle the coin without damaging it
- A reference image or guide showing DCAM proof Susan B Anthony dollars
- Optional: A coin grading scale or calipers for measuring thickness and diameter
Step-by-Step
- Understand what a DCAM proof coin is: DCAM stands for Deep Cameo, which means the coin has frosted, matte design elements that contrast sharply against a highly reflective, mirror-like background. Proof coins are struck multiple times with specially prepared dies to create this effect.
- Confirm the coin is a Susan B Anthony dollar: Check for the distinctive features: the portrait of Susan B Anthony on the obverse, the eagle landing on the moon on the reverse, and the inscriptions “LIBERTY,” “IN GOD WE TRUST,” and the date (1979, 1980, or 1999 for the special release). Also confirm the coin’s size is about 26.5 mm in diameter.
- Inspect the coin’s surface for mirror-like fields: Hold the coin under good light and tilt it. The flat background (fields) should reflect light like a mirror, showing clear reflections of nearby objects or light sources. This is a key DCAM trait.
- Look for frosted, raised design elements: The portrait, lettering, and other raised parts should have a frosted appearance that contrasts sharply with the mirror fields. This frosting should be even and smooth, not dull or patchy.
- Use a magnifying glass or loupe to examine details: Under magnification, the frosted areas will have a finely textured surface, while the fields will be smooth and flawless. Check for any scratches or blemishes that might affect the coin’s DCAM status.
- Check for sharpness and strike quality: Proof coins, especially DCAMs, are struck with extra pressure to create sharp details. The edges of letters and design elements should be crisp and well-defined, without softness or blurriness.
- Compare to reference images or known DCAM coins: Use reputable coin guides or online databases to compare your coin’s appearance. Authentic DCAM Susan B Anthony dollars have a distinct look that can be verified visually.
- Verify the coin’s weight and dimensions (optional): A genuine Susan B Anthony dollar weighs approximately 8.1 grams and measures 26.5 mm in diameter. While this doesn’t confirm DCAM status, it helps rule out counterfeits or altered coins.
- Consider professional grading if uncertain: If your coin exhibits DCAM characteristics but you want confirmation or certification, sending it to a professional grading service can provide an expert opinion and increase its market value.
Common Mistakes
- Confusing a regular proof with DCAM: Not all proof coins have the deep cameo contrast. Some proofs have a more uniform finish without the mirror-frosted contrast.
- Misinterpreting bag marks or blemishes: Handling marks or minor scratches can be mistaken for surface texture differences. True DCAM frosting is smooth and consistent.
- Using poor lighting: Inadequate or colored light can obscure the mirror finish and frosting, making identification difficult.
- Ignoring coin wear: Circulated or worn coins lose their DCAM appearance, so only uncirculated proofs can qualify.
- Relying solely on weight or size: While important, these measurements don’t confirm the cameo contrast or proof status.
- Assuming all Susan B Anthony dollars are DCAM proofs: Most Susan B Anthony dollars are business strikes, not proofs, and will lack cameo contrast.
Tips
- View the coin against a dark background to better see the cameo contrast.
- Use indirect lighting and tilt the coin slowly to observe changes in reflection and frosting.
- Handle the coin by its edges with gloves or a cloth to avoid fingerprints that can obscure details.
- Use multiple reference sources, including official mint photos and collector forums, for comparison.
- Store your DCAM proof coins in protective holders to preserve their condition and cameo effect.
- Familiarize yourself with the differences between DCAM and standard proofs by examining known examples in person or online.
Troubleshooting
If you are having trouble identifying whether your Susan B Anthony dollar is a DCAM proof, here are some steps to consider:
- Cannot see clear mirror fields? Check your lighting setup. Try a brighter, more natural light source or indirect lighting to reduce glare. Tilt the coin at various angles.
- Frosted areas look dull or patchy? The coin may not be a true DCAM, or it could be a damaged or circulated proof. Examine under magnification for surface texture consistency.
- Coin appears worn or scratched? DCAM proofs are uncirculated and should be free from wear. If worn, it may have lost cameo contrast. Consider grading or expert opinion.
- Unsure if the coin is a proof at all? Check the date and mint mark. Proof Susan B Anthony dollars were primarily made in 1979, 1980, and a special 1999 issue. Business strikes lack cameo contrast.
- Still uncertain about identification? Consult with a professional coin dealer or submit the coin for grading. Experts can confirm DCAM status and verify authenticity.
