What moves the price of this card
The Ancient Technical Machine Steel on this page is the only printing from Japanese Undone Seal, and it has not sold once yet. The cheapest copy anyone has listed is $4.99£3.74€4.35. Only one printing of this card was produced, so there is no cheaper version to confuse it with.
That number is what a seller is asking, not what anybody paid, and the difference matters most on a card this new. Presale listings open high because whoever holds the only copy sets the price, and they settle over the first weeks after release as enough copies change hands for TCGplayer to mint a market price. This page swaps to that figure the day it exists, and the grade ladder and sold list fill in behind it.
