I’ve Seen These Mistakes Over and Over – Here’s How to Avoid the Pitfalls
After thirty years in coin collecting, I’ve lost count of how many collectors burn cash on modern MS68 errors. Whether you’re competing in registry sets or building an investment portfolio, these five mistakes keep costing people money. The good news? I’ll show you how to spot them – and fix them if you’ve already slipped up.
Mistake #1: Ignoring the ‘Modern’ Definition Trap
The Warning Signs
New collectors often throw all post-1965 coins into the same “modern” bucket. Big mistake. Just last month, a client overpaid by $1,200 for a 1980s MS68 thinking it held the same value as a 2010s issue.
What Not to Do
- Never assume grading standards match across decades
- Skip mintage comparisons between different eras
Recovery Strategy
Divide your research: treat 1965-1999 as “transitional” coins and 2000-present as “true” moderns. Check PCGS/NGC population reports separately for each group.
Mistake #2: Chasing Top-Pop MS68s Blindly
The Warning Signs
That “1/0” designation makes hearts race – until three more surface. I’ve watched collectors pay $5,000 premiums for coins that became common within six months.
What Not to Do
- Don’t bite on freshly-discovered top pops
- Steer clear of coins where MS69 grades are plentiful
Recovery Strategy
If you own one of these time bombs, sell when registry collectors are competing. For new buys, target coins holding their top-pop status for five years minimum.
Mistake #3: Overlooking Eye Appeal in MS68s
The Warning Signs
I can’t tell you how many “technically perfect” MS68s hide ugly secrets:
• Milky silver spots
• Blotchy toning
• Visible scratches under bright light
What Not to Do
- Never buy raw MS68s without a 10x loupe
- Avoid slabs where plastic obscures the surfaces
Recovery Strategy
Got a flawed MS68? Professional conservation might help it cross to higher grades. Problem-free coins often upgrade with careful resubmission.
Mistake #4: Misjudging the Toning Premium
The Warning Signs
Modern coin toning plays tricks. Last year, a collector paid $3k extra for “rainbow” tones that turned brown within eighteen months. Watch for:
• UV-light reactions (artificial coloring)
• Color concentrated near holder edges
• Toning that hides contact marks
What Not to Do
- Never skip the UV flashlight test
- Walk away from toning covering imperfections
Recovery Strategy
If you overpaid for pretty colors, sell while the tones are vibrant. For new purchases? Stick to NGC/PCGS-certified natural toning only.
Mistake #5: Ignoring the Crack-Out Potential
The Warning Signs
Most collectors miss golden opportunities with:
• Strictly graded series (like modern commemoratives)
• Coins that could cross to higher grades
• Raw coins desired by album collectors
What Not to Do
- Don’t treat the slab as gospel
- Avoid paying full price for damaged holders
Recovery Strategy
Hunt for undervalued MS68s with strong technicals. I recently turned a $800 purchase into $2,300 by cracking out a Roosevelt dime for a type set collector.
The Smart Collector’s MS68 Strategy
After helping hundreds of collectors avoid these traps, here’s my no-nonsense approach:
- Focus on 1970s-1990s coins where MS68 is scarce
- Buy only flawless-looking coins (no milk spots!)
- Target series where MS69/70s are still rare
- Check crackout potential before buying
- Always triple-check population reports
Remember – every collector makes mistakes. I’ve made plenty myself. The key is spotting them early and using these recovery tricks. MS68 coins can be golden opportunities when you sidestep these common errors.
