Start with the market. Save the cards that matter to you.
CardTrends displays available source data and does not appraise or broker cards. PSA population is certified supply, not the number of copies for sale. Pokemon, PSA, and other third-party marks belong to their respective owners; CardTrends is not affiliated with or endorsed by them.

Market context for the exact card in front of you.
CardTrends organizes Pokemon card prices, completed-sale evidence, population data, market activity, and collector discussion around one precise identity: card, set, printing, and condition or PSA grade.
What we cover
We provide available Near Mint, PSA 9, and PSA 10 prices across approved mainline sets, with deeper sales and population evidence for selected, actively traded cards.
How we work
Scheduled data pipelines collect licensed or permitted source data, normalize card identity and price dimensions, validate releases, and publish source-labeled observations.
One connected market view
A card price is more useful beside its source, observation date, completed sales, certified population, and current market activity. CardTrends brings those pieces together instead of treating price lookup, research, news, and collector conversation as separate products.
- Browse mainline sets and compare available Near Mint, PSA 9, and PSA 10 prices.
- Open canonical card pages tied to a specific set, number, printing, and grade.
- Inspect source names, dates, quote status, observed sales, and PSA population where available.
- Follow cards through a watchlist, portfolio, Market Pulse, specialist news, and community posts.
Built for traceability, not just lookup.
Identity first. Similar names, printings, variants, and grades remain separate instruments.
Source visible. Prices retain their provider, observation date, support count, and quality state.
Evidence separated. Asking prices, aggregate market summaries, and completed sales are not presented as interchangeable facts.
Coverage is explicit. Missing data stays missing, and deeper research is limited to cards with enough market evidence.
CardTrends is a public beta.
