How this is worked out
The week runs Monday Aug 17, 2026 to Sunday Aug 23, 2026. Index closes are the published daily level on each Sunday; the week change is Sunday against the Sunday before. Sales are every eBay US sale of an English Pokémon card UltraBall’s exact-card matcher verified, dated by the sale, with sales flagged unusual left out; “sold value” adds up the sales whose price paid is known, so a Buy It Now listing that took an offer is counted as a sale but not in the value. The biggest-sales list excludes those offer sales for the same reason.
Auction and Buy It Now figures are the median of sale price ÷ UltraBall’s price for the exact copy over the week’s sales of that format. The PSA 10 premium is the Sunday point of the daily premium line. Live listings are the stored Sunday readings where they exist. This record was written Oct 12, 2026 and is rebuilt once, the Monday after, as late-observed sales arrive; then it is fixed. Full method on the methodology page; version ub-weekly-1.
