PriceCharting (Pokemon)

PriceCharting is best known for its retro video-game pricing data, but it maintains an extensive Pokemon TCG section as well. Each card has a dedicated page showing current and historical pricing for raw, PSA 9 and PSA 10 grades, sourced from a mix of eBay sold data and other marketplaces.

The historical price charts are a useful complement to TCGPlayer's market price for spotting longer-term trends in card values.
