Is Your Old School B&Ms Real? How to Spot a Fake

Introduction

In today’s market flooded with counterfeits, knowing the specific diagnostic points for this item is critical. The nostalgic memories shared by collectors about the golden era of brick-and-mortar coin shops reveal not just the charm of those times, but also the importance of authentication skills that every collector should master.

Historical Significance

The B&M coin shops of yesteryear were treasure troves of numismatic history. Collectors fondly remember the rotating trays, red velveteen displays, and the distinctive smell of old coins mixed with tobacco smoke. These shops weren’t just retail spaces—they were community hubs where knowledge was shared and collections were built one coin at a time.

Identifying Key Markers

Weight Verification

Authentic B&M coins should match their expected weight specifications. Use a precision digital scale that measures to at least 0.01 grams. For silver coins, the weight should align with their silver content plus the base metal alloy. Any significant deviation from the standard weight is an immediate red flag.

Magnetic Properties

Most genuine B&M coins were struck in non-magnetic metals. Use a strong neodymium magnet to test your coins. Silver, gold, and copper coins should not be attracted to the magnet. If you detect magnetic attraction, you’re likely dealing with a counterfeit made from magnetic steel or other ferrous metals.

Die Markers and Design Details

Examine the coin under magnification (10x minimum) for specific die markers. Look for:

• Unique die cracks or polishing marks
• Specific letter spacing variations
• Distinctive mint mark styles for the era
• Edge reeding patterns and consistency

Surface Analysis

Authentic B&M coins often show natural toning patterns that developed over decades. Be wary of coins with:

• Artificially applied toning
• Uniform coloration across the surface
• Evidence of recent cleaning or dipping
• Inconsistent luster patterns

Common Fakes and Their Characteristics

Cast Counterfeits

Cast fakes often show:

• Pitting or porosity on the surface
• Soft, indistinct design details
• Irregular weight distribution
• Visible casting seams

Struck Counterfeits

Modern struck counterfeits may exhibit:

• Incorrect metal composition
• Wrong die alignment
• Modern minting technology traces
• Inconsistent strike quality

Altered Date and Mint Mark Fakes

Common alterations include:

• Tool marks around date digits
• Inconsistent patina in altered areas
• Mismatched mint mark styles
• Evidence of metal removal or addition

Testing Methods

Specific Gravity Test

For silver and gold coins, perform a specific gravity test:

1. Weigh the coin in air
2. Weigh the coin suspended in water
3. Calculate specific gravity using the formula
4. Compare results to known standards

Sound Test

Genuine silver coins produce a distinctive ring when gently tapped. Counterfeits often produce a dull thud or different pitch.

Edge Inspection

Examine the coin’s edge under magnification for:

• Consistent reeding depth and spacing
• Absence of casting seams
• Proper metal flow characteristics
• Consistent edge thickness

Advanced Testing

Consider professional testing methods:

• XRF (X-ray fluorescence) analysis
• Ultrasound thickness testing
• Microscopic die wear analysis
• Metallurgical composition testing

Authentication Checklist

Before purchasing any B&M coin, verify:

• Weight matches specifications
• Magnetic properties are correct
• Die markers align with known authentic examples
• Surface characteristics are natural
• Provenance can be traced

Red Flags to Watch For

Be immediately suspicious of:

• Coins priced significantly below market value
• Sellers unwilling to provide detailed photos
• Coins with inconsistent toning or luster
• Missing or incorrect mint marks
• Unusual edge characteristics

Professional Authentication Resources

When in doubt, consult:

• Professional grading services (PCGS, NGC, ANACS)
• Experienced numismatists
• Authentication forums and communities
• Reference books and catalogs

Conclusion

The B&M coins from the golden age of coin collecting represent not just monetary value, but historical significance and nostalgic memories. By mastering authentication techniques and understanding the specific markers of genuine pieces, collectors can protect themselves from counterfeits while building meaningful collections. Remember that authentication is both a science and an art—combining technical knowledge with experience and intuition. Whether you’re a seasoned collector or just beginning your journey, the skills you develop in authentication will serve you well throughout your numismatic pursuits.

Happy collecting, and may all your B&M acquisitions be authentic treasures!
