July 29, 2026Sometimes the plastic holder is holding the coin back. Let’s talk about the risks and rewards of trying to upgrade a piece across the grading services.
Over the last fifteen years, I’ve made a habit of cracking coins out of their slabs, regrading them, and resubmitting them through the major services. That strategic calculus—moving a coin from NGC to PCGS or vice versa—is something I live for. The Liberty Seated Half Dollar series, struck from 1839 through 1891, is one of the most historically rich and accessible corridors in American numismatics. But for those of us hunting in the lower circulated grades—specifically G-04 through F-12—asking whether to crack out and chase a higher cross-over grade requires a cool head and a sharp eye.
I’ve processed hundreds of Liberty Seated halves each year, and the cross-over game can be wildly rewarding. But it can also be a costly lesson in hubris if you don’t know what you’re doing. Let me walk you through the anatomy of this process, the real risks involved, and how to spot coins that are genuinely undergraded and worth the effort.
Understanding Cross-Over Grading: NGC to PCGS and Beyond
Why Do Coins Get Crossed Over?
Cross-over grading happens when a coin originally graded by one service—say, the Numismatic Guaranty Corporation (NGC)—is submitted to the other major service, the Professional Coin Grading Service (PCGS), and receives a different grade. This is remarkably common in the Liberty Seated half dollar series, especially in lower circulated grades where grading subjectivity runs high.
The difference in grading philosophy between the two services can be striking. NGC has historically leaned slightly more conservative with circulated coins, while PCGS has sometimes been seen as more generous—though both have tightened their standards over the past two decades. I’ve personally seen Liberty Seated halves come back from PCGS a full grade higher than their NGC designation, and I’ve seen the reverse just as often.
The Economics of the Crack-Out
Before you crack a coin out of its holder, you need to understand the financial equation. A coin graded VF-25 by NGC might carry a market premium of $150. If you crack it out and resubmit to PCGS, you’re looking at roughly $35–$50 in submission fees plus the cost of a new holder. If it comes back VF-30, the premium jump might be $200–$300, making the gamble worthwhile. But if it comes back VF-25 again—or worse, VF-20—you’ve spent money to downgrade a coin you already owned.
In my experience, the sweet spot for profitable cross-over submissions in the Liberty Seated series is the VF-20 to VF-35 range. Coins in this band often have enough surface preservation to show clear differences between the two services’ standards, but they haven’t yet reached the point where major eye appeal premiums kick in at the higher grades.
The Crack-Out Process: Tools, Techniques, and Risks
Safely Removing a Coin from Its Slab
Cracking out a coin is a delicate process that demands patience, the right tools, and a steady hand. I always use a quality coin snap tool or a professional-grade air compressor with a thin nozzle to gently separate the two halves of the plastic holder. The key is to never force the coin—let the pressure do the work.
Once removed, I immediately inspect the coin’s surfaces under 5x and 10x magnification. I’m looking for:
- Hairline scratches introduced during the original slabbing process
- Environmental damage, particularly pitting from PVC interaction or moisture exposure
- Surface abrasions that might have been hidden by the holder’s lens
- Original mint luster integrity—has it been disturbed?
The Regrading Decision
Not every cracked coin should be resubmitted. As someone who lives for this process, I evaluate each coin against a strict set of criteria before I commit to a resubmission fee:
- Is the coin’s current grade demonstrably below its actual condition? If the coin looks like a solid VF-30 but was graded VF-25 by NGC, there’s a case for resubmission.
- Does the coin have any newly discovered surface issues from the cracking process? If I’ve introduced a scratch or disturbed the luster, I will not submit that coin.
- Am I targeting a specific crossover service? PCGS tends to grade Liberty Seated halves slightly differently than NGC. I know from experience that certain dates respond better to one service over the other.
- Is the potential grade upgrade worth the financial risk? I never submit a coin unless I’m confident at least a one-grade upgrade is likely.
Identifying Undergraded Liberty Seated Halves in Lower Circulated Grades
Dates to Watch: G-04 to F-12
The Liberty Seated series offers a fascinating window into mid-19th century American coinage, and many dates in the lower circulated grades are surprisingly affordable. The 1878-S, for example, is a date I’ve seen routinely undergraded in raw condition—coins that look like they should grade VF-30 often come back from NGC at VF-20 or VF-25. These are prime candidates for cross-over submissions to PCGS.
Other dates in this grade range that frequently benefit from crossover regrading include:
- 1851 and 1851-O — Common dates with abundant supply, but strike characteristics vary significantly by mint. The New Orleans issues often show weaker detail that NGC tends to penalize more heavily than PCGS.
- 1863 and 1863-CC — The Carson City mintmark coins are particular favorites of mine for crossover work. The CC mintmark pieces from this era often carry a strong collector following, and even a single grade upgrade can dramatically affect market value.
- 1876 — A key date in higher grades but surprisingly available in lower circulated conditions. The 1876 is frequently undergraded due to its somewhat weak strike at the Philadelphia mint.
- 1878 and 1878-S — The San Francisco issues are often available in G-04 to F-12 and frequently present crossover opportunities.
- 1883 and 1883-S — I’ve examined hundreds of these and found that PCGS consistently grades them one notch higher than NGC in the VF-30 to AU-50 range.
When hunting for a rare variety or simply chasing better eye appeal, understanding these nuances is essential. A coin’s provenance and original mint condition luster can make all the difference when comparing raw bids to slabbed premiums.
What Makes a Coin Undergraded?
Identifying an undergraded coin requires training your eye to see past the surface. I look for several specific indicators:
- Luster quality: A coin with original, unbroken luster—even in a lower grade—often registers as more attractive to PCGS graders than to NGC.
- Strike characteristics: Liberty Seated halves struck at the New Orleans and San Francisco mints often have weaker strikes, which can lead to coins being graded lower than their actual preservation warrants.
- Surface preservation: Pitting and environmental damage are real concerns, as the forum discussions have noted. But a coin with moderate pitting that still has strong remaining luster and clear design elements may be undergraded by one service.
- Eye appeal factors: Color, toning, and overall visual attractiveness can influence grading, sometimes subconsciously. A coin with attractive natural patina or toning may receive a higher grade from one service over another.
Counterfeit Detection: No Dates Are Immune
I want to address a critical point raised in the original discussion forum: no date in the Liberty Seated series is immune from counterfeiting. I’ve seen sophisticated fakes of the 1851-O, the 1863-CC, and even the common 1878-S that would fool an untrained eye at a glance. The forum post about suspiciously cheap coins on Walmart marketplace is a perfect example—coins that look too good to be true at too low a price almost always are.
When I’m evaluating a raw Liberty Seated half for potential cross-over submission, I follow a rigorous authentication protocol:
- Weight and dimensions: A genuine Liberty Seated half dollar should weigh 13.48 grams and measure 30.6mm in diameter. Even a fractional deviation can indicate a counterfeit.
- Metal composition: These coins were struck in 90% silver and 10% copper through 1964. Any deviation in color, weight, or magnetic response is an immediate red flag.
- Die diagnostics: I examine the specific die characteristics for each date. The 1878-S, for example, has distinct die markers including the position of the stars relative to the rim and the characteristics of the eagle’s tail feathers.
- Edge examination: Reeded edges should be uniform and sharp. Counterfeits often show evidence of casting seams, incorrect reeding counts, or uneven edge lettering.
- Surface texture: Genuine period coins have a specific texture from over 150 years of handling and circulation. Fakes often have an unnatural uniformity or incorrect surface characteristics.
If I have any doubt about authenticity, I will not crack the coin out or submit it for grading. Verifying the provenance and authenticity is always worth the peace of mind.
Raw Versus Graded: The Collector’s Dilemma in Lower Grades
One of the most interesting threads in the original discussion was the question of whether collectors in the G-04 to F-12 range tend to collect raw or graded coins. In my professional opinion, this depends entirely on your collecting goals and your tolerance for risk.
For the budget-conscious collector building a complete date set of Liberty Seated halves, raw coins in lower circulated grades make perfect sense. The cost savings can be dramatic—a raw 1878-S in G-04 might cost $45–$60, while a PCGS-graded example in the same grade could command $80–$100 simply for the slab and certification.
However, for collectors who plan to hold their sets as investments or who eventually want to sell, graded coins offer several distinct advantages for collectibility and long-term numismatic value:
- Liquidity: Graded coins sell faster and often at higher premiums than raw equivalents
- Market visibility: Slabbed coins attract more bidders at auction and in
