Grading SBA PR70 DCAM Coins: The Microscopic Margin Between Perfection and Reality

For collectors, few moments rival the thrill of holding a pristine Susan B. Anthony Proof – especially one that might achieve the coveted PR70 DCAM designation. But what separates a true gem from an “almost perfect” specimen? Let’s examine how grading experts scrutinize these modern treasures, where even microscopic flaws can mean the difference between a modest collectible and a numismatic showstopper.

The PR70 DCAM Standard: Chasing Perfection

Struck between 1979 and 1999, the Susan B. Anthony dollar broke new ground as America’s first small-sized dollar and the initial circulating U.S. coin to honor a real woman. Today, Proof specimens graded PR70 Deep Cameo (DCAM) by PCGS or NGC represent the holy grail for modern collectors. These coins aren’t just beautiful – they’re studies in minting perfection. To earn this pinnacle grade, they must boast:

• Mirror-like fields darker than a moonless night
• Frosted devices so crisp they appear sculpted in fresh snow
• A strike sharp enough to shave with
• Zero post-production marks visible even under 5x magnification

The Naked Eye Doesn’t Lie

True PR70 DCAM coins possess a magical depth that makes Susan B. Anthony’s portrait seem to float above the fields. Achieving this requires:

• 0-2 invisible flaws (we’re talking micron-level imperfections here)
• Deep cameo contrast that survives generational shifts in lighting technology
• Unbroken luster flowing like liquid across every millimeter
• Pristine fields that reveal nothing – not even your reflection’s secrets – under angled light

The Telltale Stain: A Collector’s Nightmare

Face Value Takes On New Meaning

A recent forum discussion spotlighted every collector’s fear: a vertical discoloration marring the critical left cheekbone-to-ear transition zone. On SBA dollars, this high-relief area acts like a fingerprint for minting quality. That faint shadow you can see without magnification? It’s not just a flaw – it’s a death sentence for PR70 dreams.

“We’ve all been there – that sinking feeling when you spot something the graders missed. Modern proofs get about three seconds of scrutiny. Sometimes a 69 sneaks into a 70 holder.”

Four Silent Killers of Proof Perfection

While proofs shouldn’t show wear, human hands often leave cruel calling cards:

• “Fingerprint fossils” from careless handling before encapsulation
• Carbon spots blooming like mold on a vintage photo
• PVC haze creating a milky veil over the mirror fields
• Drag lines from well-intentioned but disastrous cleaning attempts

The Cameo Dance: When Frost Meets Mirror

The DCAM designation demands more than contrast – it requires visual electricity. The frost on Susan’s portrait shouldn’t just contrast with the fields; it should snap like a winter morning. When you rotate the coin, the mirrored background should transform from obsidian black to liquid mercury while the frosted devices maintain their crisp, white purity.

That stubborn discoloration in our case study? It’s camping right in the Mona Lisa’s smile of SBA proofs. The location suggests three possible tragedies:

• A minting hiccup during the frosting process
• Post-strike contact wearing the delicate frosted surfaces
• Chemical reactions creating a permanent shadow puppet on Liberty’s face

Strike Zone: Where Details Make or Break Value

A true PR70 SBA isn’t just clean – it’s crisper than a new dollar bill. Graders demand:

• Hair waves above the ear showing individual strands
• Collar and neckline separation sharper than a suit’s pressed crease
• Radial leaf veins in the wreath visible without squinting
• “LIBERTY” so pronounced you could read it by moonlight

Our problem coin’s adequate strike only heightens the tragedy – its flaws can’t be blamed on weak minting, making that cheek stain even more damning.

The TPG Tango: PCGS vs NGC Approaches

While both giants share nearly identical standards, seasoned collectors know:

• PCGS plays hawk-eyed detective with field marks
• NGC falls hardest for dramatic cameo contrast
• Both will bench any coin with naked-eye flaws at the PR70 level

From Coffee Money to Car Payment: The Grade Premium

The chasm between PR69 and PR70 DCAM turns pocket change into prized possessions:

The forum coin’s visible flaw likely drops it to PR68-PR69 territory – a $30 pretender in a $1,000 suit.

Your Battle Plan for Suspect Slabs

When your gut says “something’s off”:

1. Inspect like a jeweler – 10x magnification against grading service photo archives
2. Seek a second opinion from ANACS or ICG
3. Request returns if certification photos don’t match
4. Consider crossover submissions only if you’ve found grading ironclad evidence

“Life’s too short for ‘almost perfect’ coins. Hold out for one that makes your heart skip a beat.”

The Final Verdict: Beauty in the Beastly Details

True SBA PR70 DCAM specimens represent the pinnacle of modern proofing artistry – numismatic lightning captured in a 26.5mm capsule. Our case study coin serves as a sobering reminder: in ultra-grade moderns, perfection tolerates no compromises. For registry set warriors and type collectors alike, remember this motto: “The loupe giveth, and the loupe taketh away.” Your 10x magnifier isn’t just a tool – it’s the truth-teller separating marketing fantasy from numismatic reality.
