Pokémon card market data you can cite
Original figures from UltraBall’s own data: 10 daily indexes built from verified sales, the largest sales on record, what trades most, what a PSA 10 adds, what is for sale on eBay right now and how auctions price against fixed listings. Each page keeps its URL, states its method, carries a CSV and a chart you can publish, and says when it was last updated.
