Different grading companies and card markets pay different premiums. Avoid declaring “grading adds value” without a specific card and grade.
- Record the raw benchmark: Use recently completed sales for the identical printing in a credible condition range.
- Model graded outcomes: Build pessimistic, central and optimistic grade cases using sold results, not advertised buy-it-now prices.
- Subtract the whole process: Grading, shipping, insurance, marketplace fees and any additional handling belong in the comparison.
