Authentication Guide: Detecting Counterfeit PCGS Old Green Holders

The Authentication Challenge

With counterfeits flooding the market, knowing the specific diagnostic points for PCGS Old Green Holders (OGH) is critical. These vintage holders represent a significant era in coin collecting, and their authentication requires understanding both the physical characteristics and the potential damage from aftermarket handling.

Historical Significance of PCGS OGH

PCGS introduced their Old Green Holders in the early 1990s, featuring a distinctive green label and holographic security elements on the reverse. These holders were produced until approximately 2008, when PCGS transitioned to newer designs. The holographic feature was designed to prevent counterfeiting, but as collectors have discovered, the hologram’s placement on the exterior of the holder created a vulnerability that auction houses and dealers have exploited.

Key Authentication Markers

Authentic PCGS OGH slabs contain several critical authentication features that counterfeiters struggle to replicate perfectly:

Weight and Dimensions

• Standard PCGS OGH slabs weigh approximately 85-90 grams
• Dimensions are precisely 63mm x 76mm x 13mm
• The plastic should feel substantial and rigid, not flimsy

Holographic Properties

The hologram on authentic OGH holders exhibits specific characteristics:

• Multi-dimensional appearance when tilted under light
• Distinct color shifts from gold to green
• PCGS logo and denomination text visible within the hologram
• Microprinting that becomes visible under magnification

Magnetic Properties

Testing for magnetic properties can help identify fakes:

• Authentic PCGS holders are non-magnetic
• If a strong magnet is attracted to the holder, this is a red flag
• Some sophisticated counterfeits use magnetic materials to add weight

Common Fakes and Variations

Counterfeiters have become increasingly sophisticated in replicating PCGS OGH holders. Understanding the most common fakes is essential for authentication:

Basic Replica Holders

These are the most common fakes, often produced in China and sold online. They typically feature:

• Poor quality holograms that appear flat or one-dimensional
• Incorrect font usage on labels
• Inconsistent spacing and alignment
• Wrong weight or dimensions

“Improved” Counterfeits

More sophisticated fakes that have appeared in recent years include:

• Better quality holograms that require careful examination
• Correct weight achieved through metal inserts
• Accurate dimensions but incorrect plastic composition

Altered Authentic Holders

Some fraudsters purchase authentic OGH holders and alter them:

• Replacing the coin with a counterfeit
• Changing the grade on the label
• Adding fake toning or damage to increase perceived value

Testing Methods for Authentication

Several testing methods can help authenticate PCGS OGH holders:

Visual Examination

Begin with careful visual inspection under good lighting:

• Examine the hologram for dimensional qualities
• Check label printing for sharpness and color accuracy
• Look for signs of tampering around the edges
• Verify the coin matches the holder’s indicated grade

Weight Verification

Use a precise digital scale to verify weight:

• Authentic OGH should weigh between 85-90 grams
• Significant deviation suggests a counterfeit
• Be aware that sophisticated fakes may use metal inserts to achieve correct weight

Magnetic Testing

Simple magnetic testing can reveal many fakes:

• Use a strong rare-earth magnet
• Authentic holders should show no magnetic attraction
• Any magnetic response is cause for suspicion

Ultraviolet Light Examination

UV light can reveal characteristics invisible under normal lighting:

• Authentic PCGS holders may fluoresce in specific patterns
• Fakes often show different UV characteristics
• Look for inconsistencies in fluorescence across the holder

Die Markers and Production Details

Examine specific die markers and production details:

• Check for the correct font and spacing on the label
• Verify the hologram design matches known authentic examples
• Look for the correct edge design and texture

Damage from Dealer Stickers

The forum discussion reveals a significant issue with dealer stickers damaging the PCGS hologram. This damage can actually serve as an authentication marker in some cases:

Types of Hologram Damage

Based on collector reports, hologram damage from stickers typically manifests as:

• Flaking or peeling of the holographic layer
• Cloudiness or discoloration where stickers were applied
• Complete removal of the holographic material

Authentication Through Damage

Interestingly, hologram damage from stickers can actually help authenticate a holder:

• Counterfeit holders typically don’t show this specific type of damage
• The pattern of damage often matches known sticker sizes from major auction houses
• Authentic damage shows signs of adhesive residue consistent with sticker removal

Dealer Practices and Authentication

The discussion highlights varying dealer practices:

• Some dealers like Great Collections avoid placing stickers on the hologram
• Others place stickers directly over the hologram, causing damage
• The pattern and location of damage can indicate which dealer handled the coin

Removal Techniques for Dealer Stickers

For collectors who wish to remove dealer stickers, several methods have been discussed:

Oil-Based Removal Methods

The most recommended approach involves oil-based solvents:

• Paraffin lamp oil soaks
• Goo Gone application
• Mineral oil treatment
• WD-40 (applied carefully away from the coin)
• Vegetable or olive oil for less aggressive removal

Removal Process

Proper sticker removal technique:

1. Apply oil to the sticker and let it soak for several hours
2. Attempt gentle removal after adhesive has softened
3. For paper stickers, the oil may soak through the surface
4. For glossy or plastic stickers, scuffing the surface first may help
5. Clean residual adhesive with additional oil and a soft cloth

Damage Prevention

To prevent hologram damage when applying stickers:

• Use smaller stickers placed off to one side
• Avoid covering the hologram entirely
• Consider placing stickers on the coin’s flip rather than the holder

Value Guide and Market Considerations

The condition of the PCGS holder significantly impacts value:

Perfect OGH Holders

Highest premium applies to holders with:

• Intact, undamaged hologram
• No sticker residue or damage
• Clear, unblemished label

Damaged OGH Holders

Moderate premium applies to holders with:

• Minor hologram damage from sticker removal
• Small areas of adhesive residue
• Minor scratches on the plastic

Significantly Damaged Holders

Reduced premium or no premium applies to:

• Extensive hologram damage or removal
• Large areas of sticker residue
• Cracked or chipped holders

Conclusion: The Importance of Authentication

PCGS Old Green Holders represent a significant era in coin collecting, and their authentication requires attention to multiple factors. The discussion among collectors reveals both the challenges of dealing with aftermarket damage and the importance of proper handling practices. By understanding the specific diagnostic points covered in this guide – weight, magnetic properties, die markers, common fakes, and testing methods – collectors can better protect themselves from counterfeits while appreciating the historical significance of these vintage holders.

The evolution of dealer practices, as highlighted in the forum, also demonstrates how the collecting community continues to adapt to preservation challenges. Whether you’re a seasoned collector or new to OGH holders, this authentication knowledge is essential for making informed decisions in today’s market where counterfeits continue to become more sophisticated.
