The Record-Breaking Coin
In a jaw-dropping sale, a 1980-S Susan B. Anthony Dollar graded PCGS PR-70DCAM sold for $7,115,000. This makes it the only 1980 coin to ever break the million-dollar mark.
So, what makes this coin worth more than most houses? Let’s break it down 
Key Identification Features
Mint Mark Verification
- Must have “S” mint mark (San Francisco)
No “P” or “D” coins qualify
Error Characteristics
- Double Struck Obverse – visible doubling around the portrait rim
- Misaligned Die – about 15% off-center secondary impression
- Broken Collar – produces an irregular edge reeding pattern
Proof Specifications
- Mirror-like fields (deep cameo finish)
- Frosted devices (letters & portrait)
- Weighs 8.1 grams – confirm with a precision jeweler’s scale
How to Spot the $7 Million Error
Step 1: Surface Inspection
Use a 10x magnifier to check for:
Dual concentric rings around the edge
“Ghost” secondary image of the portrait
Misaligned obverse/reverse designs
Step 2: Edge Examination
Look for:
Incomplete reeding (smooth gaps)
Variable thickness (2.8–3.1 mm)
No seam lines (casts = instant fake)
Step 3: Weight & Balance Test
Measurements must be exact:
- 8.1 grams (±0.01g)
- 26.5 mm diameter
- 2.0 mm thickness at center

Warning: Common Fakes
Be cautious – most “rare” 1980 coins are worthless replicas. Watch out for:
Electroplated copies (wrong weight & sound)
Altered mint marks (tool marks visible under microscope)
Cast replicas (lack crisp details)
Verification Process
To confirm authenticity:
- Submit to PCGS or NGC under “Errors & Varieties” service
- Request XRF metal composition testing
- Research provenance through Mint records
