Background

Thunderclap Spark is the Japanese Pokémon TCG standard booster box filed as SM7a. CARDZ keeps it in the ptcg-jp group. The trailing letter in the set code belongs on this slip; it is not a plain SM7 row.

The catalog id marks a standard booster box. The desk records the sealed Japanese case as one unit. An English box that only shares a storm theme is another SKU.

This packet has no sale, population, or reference price. Rank 139 is sealed-board position only. Keep Thunderclap Spark, SM7a, and the Japanese print together.

METHOD & DATA

How the BOX reference price is built

Each BOX rank uses a reference price. The method prefers completed sales. A market reference is used when sold evidence is thin. An ask floor is only a fallback, never treated as a completed sale.

Sold
Completed box sales captured inside CardZ Marketcap tracked coverage. Lots are unitised to one box, extreme outliers are dropped, and what remains is reduced to a median.
Market reference
A published market reference for that exact set, language and print wave when sold coverage is insufficient.
Ask floor
The current ask floor is shown only as a secondary reference. It does not replace a sold or market figure. A missing value stays missing, never zero.
