About Riffle
card market intelligence
Riffle is an independent price-reference and market-analytics tool for Pokémon trading cards. We track every card across the sets we cover: currently 137 sets and 18,700+ cards. We publish what the market is actually doing: estimated prices, grading data, and live-listing deals.
Where the numbers come from
Prices are collected daily from multiple market sources and published as an estimated range: our own derived figure, not any vendor’s exact price. Supply, demand, and sell-through signals come from daily captures of live eBay listings. Grading data comes from the PSA population census, captured monthly. Everything estimated is labeled “(est.)”.
Value buys
The value buys page surfaces live eBay listings priced meaningfully below a card’s own typical market level, with shipping included and obvious mismatches filtered out. Links go directly to the eBay listing.
Who builds this
Riffle is built and run by Victor, a solo independent developer: one person writing the data pipeline, the pricing models, and the site itself.
That keeps it honest and fast to improve: when something is wrong or missing, there is no queue between you and the person who can fix it. Riffle is independent and isn’t owned by or affiliated with any marketplace or grading company.
