Value concentrates hard: across 481 measured Yu-Gi-Oh! sets, the single top card typically holds about 13% of a set's total card value.

New Yu-Gi-Oh! sets have typically settled about 47% below their release-week price, with most of that easing done within roughly 13 weeks (measured across 49 recent releases).

Over the first 30 weeks after release, that easing runs about 28% deeper than the market's own drift.
