Finding Dual-Grade NGC Slabs in the Wild: A Cherry Picker’s Guide

Introduction

You don’t always need a dealer to find this. Here is what to look for when searching through circulation or bulk lots.

The NGC Dual-Grade Mystery

Recently, an intriguing NGC slab surfaced on collector forums showing what appeared to be a dual-grade designation – MS64 on the verification site but with speculation about a possible MS63 reverse grade. This anomaly sparked a fascinating discussion about data entry errors, grading systems, and the occasional quirks that make roll hunting so exciting.

Historical Context of NGC Grading

NGC has historically used various grading notations beyond simple numerical grades. In the past, they incorporated letters like “W” for white and “T” for toned directly adjacent to the numerical grade. This practice suggests that the data entry system has fields available for additional information beyond just the primary grade.

“The data entry isn’t typing the grade on a keyboard; it’s clicking on the grade. There’s probably some manual override for some of the fields printed, but the grade?” – forum member

Identifying Key Markers

When searching through bulk lots or estate sales, keep an eye out for these potential indicators of grading anomalies:

• Slab labels with unusual character counts or spacing
• Discrepancies between the physical label and online verification
• Slab numbers that return different coins when verified online
• Labels showing notations like “MS 64 DMPL” which could explain character count issues

Common Data Entry Errors

Based on collector experiences, several types of errors can occur during the slabbing process:

1. Database entry mismatches between the physical label and online records
2. Certification numbers that reference completely different coins
3. Grade entries that don’t match the actual coin’s condition

Real-World Examples

One collector shared their experience with a coin that was properly graded and slabbed, but the database listed it as AU64 instead of the correct MS64. Even more interestingly, the certification number brought up a completely different coin from a different series and date entirely.

Another collector reported having a medal with split grading where the insert said MS63 but the website listed it as MS62, while they personally graded it as MS65.

Mechanical Error Trends

Several collectors noted that mechanical errors appear to be on the rise, possibly correlating with increased workload at grading facilities. One collector reported hitting “the jackpot” twice in just three submissions, finding grading discrepancies that led to upgrades like receiving a gold shield on a properly graded coin.

Value Guide for Error Slabs

While standard error slabs typically don’t command significant premiums, certain types of errors can be quite valuable to specialized collectors:

Authentication Tips

When you encounter a potential error slab, follow these steps:

1. Verify the certification number on the official NGC website
2. Check for any discrepancies between the label and online records
3. Examine the physical label for unusual spacing or character counts
4. Research similar known errors to establish authenticity
5. Contact NGC customer service for clarification if needed

Collecting Strategy

For roll hunters and cherry pickers, error slabs represent an interesting niche. While not all errors command significant premiums, they offer several collecting advantages:

• Often available at standard slab prices
• Provide interesting conversation pieces
• May appreciate in value as error collecting gains popularity
• Offer educational insights into the grading process

Conclusion

The NGC dual-grade mystery reminds us that even in today’s highly automated world, human elements and mechanical processes can create fascinating anomalies. For roll hunters and cherry pickers, these errors represent opportunities to find something unique without paying dealer premiums. Whether you’re searching through bulk lots, estate sales, or simply examining your own collection, keeping an eye out for these quirks can add an extra layer of excitement to the hobby. Remember that while some errors are simply mistakes, others tell stories about the evolution of grading practices and the occasional human touch in an increasingly digital world.
