- Pokémon card collectors weighing grading costs
- Worth noticing
- It marks 55/45 as a centering threshold and describes the range up to 60/40 as a grader-dependent grey zone.
Field notes
The described process uses a card photo and its name and number to set up a price comparison, then checks border centering before estimating grade outcomes. Its worked receipt separates grading, shipping, insurance, and selling costs rather than treating a grade as a guaranteed premium. The page labels its sample card and numbers as made up, and notes that centering between 55/45 and 60/40 may be judged differently.
