Data & Method

LIVE LAYER: TODAY

Current prices come from TCGplayer’s daily market-price feed (via the public TCGCSV mirror), pulled per set and matched to each product’s exact ID: the same Market Price shown on the product page, to the cent.

ARCHIVE LAYER: 2024 → NOW

The entire TCGplayer feed is snapshotted daily and archived back to Feb 2024. First-of-month snapshots are extracted for every product, giving verified quarterly points for 2024–2025 and monthly points for 2026: TCGplayer’s own numbers on those exact dates.

LAUNCH-ERA LAYER: 2021 → 2024

Older history comes from monthly closes, computed from eBay completed sales. Every series is validated against the live feed before use, and a spike filter drops lone artifact months. eBay solds running slightly under TCGplayer market is the natural spread between venues.
