Prices

TCGCSV, a daily mirror of TCGplayer data. Updated once daily. English history runs from 8 February 2024; Japanese from 11 December 2024 — the panels above are measured, not asserted.

Granularity is per printing (Normal, Holofoil, Reverse Holofoil, 1st Edition), not per condition and not per grade.

Card metadata

Set names, card numbers, rarities and images come from the same source’s catalogue.

Known limitations

  • No English data before 8 February 2024, and no Japanese data before 11 December 2024, exists anywhere in our pipeline. Those are the floors of the source’s own archive.
  • The Japanese market has one real gap: the source published nothing between 20 December 2024 and 6 January 2025. It cannot be backfilled — those days are not in the archive.
  • Prices lag the live marketplace by up to 24 hours.
  • Cards delisted from the marketplace stop receiving updates; their history remains. Each product page states how many days it has and when it last moved.
  • About 2.7% of observations are rejected as implausible and excluded from every chart and statistic — see Methodology.
  • The published “high” price is unreliable and is never charted — see Methodology.
