GradeROI, the card-grading break-even test
A calculator for deciding whether a Pokémon, One Piece, or Riftbound card is worth sending to PSA instead of selling raw.
Field notes
GradeROI organizes the grading decision around a comparison between PSA submission and raw sale value, with PSA population data and sale prices identified as the core inputs. Its homepage exposes a small sample of card-level signals rather than only broad collecting advice: each entry includes a set, card number, and gem-rate percentage. Examples include Charizard Holo Base Set Unlimited at 0% and Rufflet Black Bolt at 31%. The site also provides set browsing and a Discord link.
