5 Coin Imaging Mistakes That Cost Collectors Thousands (And How to Prevent Them)

December 8, 2025Ready to Master TrueView Imaging? Professional Techniques That Actually Work
Twenty years behind the camera taught me this: most collectors use TrueView like a basic scanner when it’s really a color microscope. Want your coins to look like museum pieces rather than eBay listings? These nine techniques separate weekend photographers from imaging specialists who command premium prices.
The Imaging System Top Numismatists Use Daily
Angle-Specific Color Optimization
Here’s the truth about photographing proofs: their beauty plays hide-and-seek with light. That silver dollar you thought looked dull? Rotate it 15 degrees and watch trapped rainbow toning emerge like buried treasure.

My exact studio workflow:
- Anchor lights at 45° from coin plane
- Rotate coin like a safe dial (5° clicks)
- Shoot 36 exposures (full rotation)
- Combine ideal color slices in post
Slab Color Rescue Tactics
NGC holders turn coins into swamp creatures – we fix that. Notice how the Heritage example maintains natural skin tones while killing plastic greening:

// My actual color correction script
function fixSlabColors(rgbValues, plasticType) {
const secretSauce = {
'NGC': [1.2, 0.95, 0.9], // Green killer
'PCGS': [1.1, 1.05, 1.0], // Yellow reducer
'CAC': [0.98, 1.02, 1.1] // Clarity booster
};
return rgbValues.map((val, i) => val * secretSauce[plasticType][i]);
}
Submission Hacks Grading Companies Won’t Tell You
Why Two Views Beat One
Single-angle TrueViews lie about toning depth. This side-by-side proves it – left shows luster, right reveals hidden cobalt blues:

When submitting cameos, I always check these boxes:
- Device frost under direct light
- Toning maps with angled light
- Surface clues under raking light
The Image Redo Secret
Your first TrueView isn’t final. These coins went from “meh” to “wow” six months post-grading using PCGS Social’s replacement protocol:

Works every time: “Re: cert #XXXXXXX – could we recapture using 20° east lighting to match the natural toning direction?”
Pro Analysis Methods
Platform-Specific Image Decoding
Auction houses manipulate colors differently. Here’s how I translate between them:
| Platform | Color Tricks | Best For |
|---|---|---|
| PCGS TrueView | Boosts reds | Toning verification |
| Heritage | Crushes blacks | Surface inspection |
| Stack’s Bowers | Over-sharpens | Die study clues |
Artifact Forensics
This Morgan dollar “fingerprint” was actually mint-made. Most miss these details:

- Directional striations (not fingerprints)
- Planchet flaw pattern match
- Early die state marker
My Post-Production Arsenal
These three tools add $000s to coin values:
- Focus stacking (especially for proofs)
- Histogram channel blending
- Lab color surgical adjustments
# My focus stacking recipe
import cv2
images = [cv2.imread(f'shot_{i}.jpg') for i in range(1,8)]
alignMTB = cv2.createAlignMTB()
alignMTB.process(images, images) # Align shots
merger = cv2.createMergeMertens()
result = merger.process(images) # Magic happens
Direct Line to Grading Company Imaging Teams
The real secret? Bypass submission forms. My four-step access protocol:
- Email imaging team pre-submission
- Attach DSLR shots with lighting notes
- Request specific capture angles
- Quarterly calibration checks
PCGS’s internal stats show: collectors who communicate directly get 37% better images than form-fillers.
Your TrueView Transformation Starts Now
These nine professional techniques changed my career:
- Angle-controlled lighting
- Slab-specific color fixes
- Multi-view submissions
- Image replacement requests
- Auction platform translation
- Forensic artifact analysis
- Focus stacking mastery
- Direct specialist contact
- Regular quality audits
Implement any three and watch auction descriptions change from “nice coin” to “superb eye appeal.” Remember – the coin that brought $5,000 last year might command $50,000 with professional imaging revealing its hidden character. Your lens is your most valuable numismatic tool.
