When a card gets flagged by CGC during the submission process, it doesn’t mean the card is rejected outright—it means the grading company has identified a potential issue that requires additional scrutiny before a grade can be assigned. In the case of a Base Set Machop, this flag might have indicated print defects, centering issues, or surface wear that needed verification before the card could receive an official grade and be sealed in a protective slab. The journey from flagged to graded represents a common challenge collectors face: understanding why their vintage cards encounter obstacles at the grading company and what it takes to get them slabbed anyway.
The Base Set Machop is one of thousands of cards that encounter this same scenario each year. Base Set cards, printed in 1999 and 2000, are particularly prone to flagging issues due to the printing technology of that era. A card might arrive at CGC with a notation that requires human review—perhaps because the centering appears marginal between two grades, or because there’s surface deterioration that could push it into a lower grade tier than initially anticipated.

What Causes CGC to Flag Base Set Cards Before Grading?
CGC’s flagging system exists as a quality control checkpoint within the grading workflow. When a card’s condition presents ambiguity—sitting on the borderline between a 7 and a 6, for example—or when there are competing factors that could justify different grades, the card gets flagged for a secondary evaluation. base Set cards frequently trigger these flags because the print quality was inconsistent; some cards rolled off the press with sharp corners and clean surfaces, while others from the same print run show wear and off-center images.
The Base Set Machop specifically might have been flagged for centering issues, which were endemic to that set. Machop’s image on the card spans a significant portion of the card face, making any centering deviation obvious. If a Machop came in with the image shifted noticeably to one side or top, CGC’s initial scan might have recommended manual review to determine whether the card still met the minimum threshold for the grade the collector requested.
Base Set Print Defects and Grading Vulnerabilities
Base Set was produced during a period when the Pokemon Company was ramping up production to meet explosive demand, and print quality consistency suffered as a result. Machop cards in particular show recurring issues: uneven ink distribution on the back, white spotting or staining from humidity exposure in storage, and the aforementioned centering problems. These aren’t defects that make the card worthless, but they complicate the grading process because they sit in gray zones.
One limitation collectors often encounter is that a card flagged for print defects might eventually receive a grade, but it may be lower than expected. A Machop that was submitted with hopes for a PSA-equivalent 7 might come back as a 6 after human review reveals that the print dots and ink pooling actually constitute visible defects rather than acceptable variation. This is why many collectors strategically submit cards: they know their card’s likely grade range and submit it for that range rather than hoping for a higher outcome.
The Base Set Machop Case Study
Consider a specific example: a Base Set Machop submitted to CGC that was initially flagged might have shown all the hallmarks of a mid-grade card—clean edges, acceptable surface, but with the image noticeably higher on the card than lower, giving a centering grade of 4-5 rather than the ideal 7-8 range. The card’s overall condition might have suggested a 6, but that centering issue triggered a flag because CGC needed to confirm whether the card should be slabbed as a 6 with centering defects noted, or whether the company should recommend rejection to the submitter. What ultimately determines whether a flagged Machop becomes a graded slab is the company’s review process.
A qualified grader examined the card in person, made a final determination on centering and all surface conditions, and issued an official grade. If the card met minimum standards for that grade (even a 5), it was slabbed. If the accumulation of issues—centering, print defects, and surface wear—collectively indicated the card was outside the acceptable range for any standard grade, the card might have been returned ungraded.
How Cards Progress from Flagged Status to Final Grade
The grading process after flagging involves a human reviewer who has authority to make final grade determinations on ambiguous cards. This reviewer doesn’t re-scan the entire card; instead, they examine the physical card against the flagging notes and the grading standards for each point value.
For a Base Set Machop, the reviewer would assess: Is the centering within acceptable parameters for the submitted grade? Do the print defects visible on the front and back fall within tolerances? Does surface wear align with the expected appearance for that grade level? One important distinction is that CGC’s grading standards evolved over the years. A Machop graded as a 6 in 2022 might have been graded as a 5 in 2015 under different standards, or vice versa. Collectors who are tracking their card’s value should understand that a flagged card that eventually received a grade was evaluated under the standards in effect at the time of grading, not at the time the card was printed or first entered a collection.
Common Reasons Cards Get Flagged and Fail Grading
Not all flagged cards become graded slabs. Some cards are returned ungraded after review reveals they fall below minimum acceptable standards. The most common reasons a Base Set card gets flagged and ultimately rejected include excessive centering issues (image more than 60% off-center), heavy surface wear or creasing, water damage or staining that affects more than 30% of the card, or combinations of multiple defects that compound to push the card outside gradable condition.
A critical warning for collectors: submitting a card you believe is borderline is a calculated risk. If CGC’s reviewer determines the card doesn’t meet the threshold for the grade you requested, you’ll receive an ungraded card back, and you’ll have paid submission fees for no benefit. This is why many experienced collectors avoid submitting borderline cards and instead focus on clearly high-quality cards (PSA/BGS equivalent 7 or higher) or cards with specific historical value regardless of condition.
Market Impact of Flagged Cards That Become Slabs
A Base Set Machop that was flagged and then successfully graded carries different market weight than a clean submission. If the flag resulted in a lower grade than the collector hoped, the market value will reflect that grade—and the potential buyer may also know the card’s history if it was recently graded.
The secondary market for graded cards prices primarily on the grade and set, not on the submission history, so a flagged Machop that received a 6 sells for approximately what any other CGC-graded Base Set Machop in a 6 sells for. However, there’s an intangible value consideration: some collectors view a card that was flagged and still received a decent grade as having been vetted more thoroughly than a card that passed through the standard submission queue without review. This can actually be a positive signal for certain cards, suggesting the grader had no remaining doubts after flagging.
Preventing Flags and Learning from the Process
The best way to avoid flagging your own Base Set cards is to understand the specific vulnerabilities of the set and card before submission. For Machop specifically, examine centering carefully—compare your card’s image placement to examples of well-centered and poorly-centered versions. If your card’s image sits noticeably off-center, prepare for a flag. Check the front and back under good lighting for print spots, stains, or discoloration.
Minor print variation is normal, but extensive white spotting or uneven ink distribution will likely trigger a flag. The Base Set Machop’s journey from flagged to graded illustrates a fundamental aspect of vintage card collecting: condition assessment is subjective at the margins, and grading companies use flags as a tool to ensure consistency. Learning from these experiences—whether the card you submitted was flagged or not—helps collectors make better submission decisions going forward. Cards that are marginally conditioned are often better left unslabbed, as the grading fee may represent a larger expense than the grade bump provides in market value.
Conclusion
A Base Set Machop that was flagged by CGC and eventually received a grade represents a successful outcome to a quality control process designed to protect both collectors and the integrity of the grading system. The flagging system isn’t a punishment; it’s a verification step that ensures borderline cards are evaluated carefully rather than receiving grades that might later be disputed. Understanding why your card was flagged—and whether it ultimately became a slab or was returned ungraded—provides valuable insight into that card’s true condition.
For collectors working with Base Set cards, the key takeaway is to assess your card’s weaknesses honestly before submission and to set realistic expectations for the grade. A Base Set Machop with centering issues, print defects, or surface wear might still receive a grade if the combination of defects remains within acceptable parameters for some grade level. But submitting with awareness of these vulnerabilities, rather than hoping a flag won’t occur, leads to better submission outcomes and fewer disappointing returns.
