I’ve Watched Collectors Ruin Coins in Old Green Holders – Don’t Make These Errors
After thirty years in coin collecting, I’ve seen more OGH mistakes than I care to remember. That excitement when you find a vintage slab? It can quickly turn to panic when you realize you’ve damaged a prized coin or wasted money. Let me share the five worst blunders I’ve seen – and how to dodge them.
Mistake #1: Not Checking Your Holder’s Generation
This is the quickest way to embarrass yourself in collector circles. PCGS changed their green holders six times! I once saw a dealer charge $500 extra for a “rare OGH” that turned out to be a modern replica. Know your generations or risk:
- Getting called out in collector forums
- Paying too much for mislabeled slabs
- Cracking a holder the wrong way
Is Your Holder a Rattler? Look For These Signs
Gen 1 holders (rattlers) are collector kryptonite. Scanning eBay last week, I spotted three misidentified rattlers in “OGH” listings. Genuine rattlers have:
Dead giveaways:
- Thick seams like plastic welding
- That distinctive coin rattle
- Cert dates before 1986
How to Avoid Generation Confusion
Bookmark the PCGS holder guide on your phone. At shows, I keep this cheat sheet handy:
Safe to Buy:
• Gen 2.X (doily holders)
• Gen 3.0 (true OGH)
• Gen 3.1 (transition labels)
Walk Away From:
• Any Gen 1 (rattlers)
• Retro labels (new fakes)
Mistake #2: Ignoring Holder Breakdown
That 40-year-old plastic isn’t immortal. I’ve held coins ruined by three types of decay:
The Silent Killer: Plastic Outgassing
Old holders can literally melt coins. Check for:
- Foggy windows (like bathroom glass)
- Rainbow tints on surfaces
- Sticky residue – worst I’ve seen was on a 1921 Morgan
When Cracks Attack
A friend once had to emergency-crack a New Rochelle commemorative when fractures spread across the holder. Now I teach collectors to inspect for:
- Fine lines near the label
- Warping in heat (never leave in your car!)
- Rim stress marks
Mistake #3: Paying Too Much Just for the Green
Don’t get swept up in OGH hype. At last month’s Denver show, I watched someone pay 60% extra for a common Mercury dime in a Gen 3 holder. Use my field-tested checklist:
Is That Premium Worth It?
Before paying extra:
- Verify the holder’s generation (see Mistake #1)
- Check if the coin’s population is actually low
- Compare recent sales of the same coin in new holders
Mistake #4: Breaking Community Rules
Numismatic forums have strict OGH etiquette. I learned this the hard way when I posted a rattler by accident – got twenty angry replies in an hour! Avoid these landmines:
Forum Forbidden Actions
- Posting rattlers: Even if it’s mint-green, Gen 1 is banned
- Multiple coin drops: One coin per thread keeps discussions focused
- Low-quality submissions: As a moderator told me, “We showcase excellence”
If You Mess Up…
Damage control works best when:
- You delete the post fast
- Publicly apologize in-thread
- Return later with verified quality content
Mistake #5: Handling Like Modern Slabs
These are historical artifacts, not plastic cases. I cringe when I see people stacking OGH holders like poker chips! Preserve them right:
Storage No-Nos
- Never lay them flat (weight causes cracks)
- Keep out of sunlight (labels fade to sickly yellow)
- Avoid sticky notes (learned this after ruining an 1895-O holder)
Safe Cleaning Method
For cloudy holders, use my numismatist-approved mix:
• 1 part white vinegar
• 3 parts distilled water
• Microfiber cloth ONLY
• Never soak - trust me, tap water leaves spots
When Disaster Strikes: Recovery Plan
If your holder fails, act fast with these pro techniques:
PCGS Reholding Service
My preferred solution for high-value coins. Yes, the $25 fee stings, but as my conservator friend notes:
“Reholding preserves the certification chain – crucial for registry sets and provenance.”
Emergency Crack-Out Steps
When a coin’s in immediate danger:
- Document holder damage thoroughly
- Use dental tools on the seam only
- Transfer to a fresh archival flip
The True OGH Philosophy
As a veteran collector told me while admiring a frosty Mercury dime:
“It’s not about the plastic shell – it’s about preserving history.”
Avoid these five mistakes and your OGH coins will maintain both value and legacy. Remember: the green holder enhances your coin’s story – it shouldn’t become the whole plot.
