How these prices work

Each price is TCGplayer's near-mint market price for that exact printing (a Reverse Holo and the plain card are different prices), read from TCGplayer's own sales history. A 30-day change only appears when at least 12 near-mint copies sold in that time, so one odd sale can't fake a move. More in how Zard Charts prices work.
