Usually, no: a mechanical label error—a grading company's mistake on the slab label—does not create a dependable premium. Treat it as a correctable certification problem, not as a valuable Pokémon card variant. A wrong grade, date, card type, or issue number may look unusual. However, it differs fundamentally from a production defect created while the Pokémon card was manufactured.

What Counts as a Mechanical Label Error?
The error must be on the grading company's label or certification record. Examples include an obviously incorrect grade, wrong date, incorrect card type, or mismatched issue number. cgc classifies these discrepancies as clerical or mechanical errors.
It instructs buyers and sellers to inspect slabs and return qualifying errors for free correction and re-encapsulation with the proper label, according to the CGC Guarantee. Other qualifying problems can include missing label information or incorrect label stock. However, CGC says information that was accurate when graded but became inaccurate because of later outside events does not qualify under its mechanical-errors policy.
Does the Mistake Create a Price Premium?
The grading-company evidence does not establish a standard premium for mechanical label errors. The documented remedy is correction, so owners should not assume the mistake increases market value. An individual novelty buyer might still find an unusual slab interesting.
That possibility does not create a reliable pricing rule, especially when the grading company may replace the erroneous label. Price the slab primarily from the correctly identified card, its legitimate grade, and relevant comparable sales. If the printed grade is obviously wrong, using it to justify a higher asking price could mislead a buyer.
Label Mistake or Genuine Pokémon Error?
A factory error is part of the card itself. A mechanical error exists only because the grading company entered or printed incorrect information. That distinction matters because dramatic production defects can sometimes command substantial premiums. CGC may also identify qualifying production errors on its certification labels, as explained in its overview of TCG production defects.
Authentication still comes first. A dramatic appearance alone does not prove that a card left the factory that way; CGC rejected one severely miscut Fossil Raichu after determining it had been deliberately cut from an uncut sheet. PSA's database provides another useful contrast. It separately identifies one 1999 Charizard as "BLACK DOT ERROR," records comparable sales, and gives a PSA 6 estimate of $777 on the card's certification page. That evidence concerns a card-production error, not a mistaken slab label.
What Should an Owner or Buyer Do?
Inspect the card, label, and online certification record together. Do not rely on a seller's use of "error slab" without identifying exactly what is wrong.
PSA directs owners who believe its label or listed item information is wrong to file a Label Correction Request. For a qualifying CGC mistake, expect the inaccurate label to be replaced during free re-encapsulation rather than preserved as an officially recognized variant.
- Confirm that the certification number matches the slab and database record.
- Compare the label's set, year, card number, variant, and grade with the enclosed card.
- Determine whether the unusual feature appears on the card or only on the label.
- Save clear photographs before requesting a correction.
- Ask the grading company for its current submission instructions.
