My Step-by-Step Guide to Identifying and Solving 7 Common Bust Coin Errors

I Stumbled Into Bust Coin Errors – Here’s How You Can Avoid My Mistakes

Let me tell you about the three weeks I lost sleep over an 1808 Bust Half Dollar. The edge lettering was missing – was I holding a fortune or a fake? After comparing notes with specialists (and plenty of dead ends), I pieced together a foolproof approach to spotting genuine errors. Want to know how I finally cracked it?

My Bust Coin Error Identification System

1. Missing Edge Lettering: When Smooth Edges Mean Big Money

My “aha moment” came when examining an unlettered edge coin like those in the Dosier collection. Here’s what I learned to check:

• Match dentil patterns to verified specimens
• Measure thickness (early planchets weren’t perfectly uniform)
• Inspect for collar marks – true errors won’t show any lettering ghosts

Hard-Won Wisdom: Only about a dozen genuine examples exist. If yours looks too clean, trust your instincts.

2. Cracking the Code on Die Breaks

That faint line on your coin’s cheek? It might be a historical fingerprint. I nearly missed this on an 1810 O-108 until I dug deeper into production records:

My verification routine:

• Track crack development across different die states
• Cross-reference with mint marriage records
• Use angled lighting to reveal hidden fractures

4 Error Types That Command Premium Prices

1. Off-Center Strikes: When Imperfections Pay Your Mortgage

My 15% misaligned 1799 Bust Dollar taught me these valuation secrets:

• 5-10% off-center: 2-5x face value
• 15-30% offset: 5-20x premium (especially with visible dates)
• 50%+ misalignment: Rare finds topping $25k

2. Double Strikes: Finding Hidden Treasure in Metal Memory

This 1805 B-3 double strike shows exactly what makes collectors swoon:

What I always inspect:

• “Dentil tracks” – repeating rim patterns
• Rotation angles between strikes
• Metal flow under magnification

Field-Tested Error Detection Methods

The Flashlight Technique That Changed Everything

After years of blurry edge photos, I nailed this simple process:

1. Grab a 5000K LED flashlight (color accuracy matters)
2. Rest coin at 45° on a soft cloth
3. Shoot through a toilet paper roll (seriously!) to kill glare
4. Capture multiple exposures to freeze details

Planchet Errors: Don’t Repeat My $2,100 Mistake

Confusing a lamination for a ding cost me big. Now I always:

• Run specific gravity tests immediately
• Check under UV light for material differences
• Compare to authenticated coins like this 1836 lamination:

My $127 Toolkit That Saves Thousands

These budget tools transformed my authentication game:

• Escala Prismo scale ($49) – detects weight discrepancies
• Plugable USB microscope ($65) – reveals microscopic details
• Neewer LED panel ($13) – perfect for garage inspections

Your Roadmap From Confusion to Confidence

Through expensive trial and error, I learned Bust errors follow patterns you can master. By: 1) Matching dies to historical records, 2) Documenting properly, and 3) Knowing what drives premiums, you’ll spot valuable errors others miss. That odd coin in your drawer? It might just fund your next vacation.
