Background

Legendary Heartbeat is the Japanese Pokémon sealed booster box on this CARDZ row, set code S3a. The SKU ptcg-jp-s3a-booster-box-std sits on the ptcg-jp line as a standard case.

Official name remains Legendary Heartbeat. Language reads Japanese from the jp stamp, and the game field is ptcg. The trailing letter in S3a is part of the filing code, not a nickname.

Rank 179 is board position only. Keep the Japanese S3a box. An English retitle or a Japanese S3 case without the letter is a different row.

Match S3a, Japanese language, and ptcg-jp before treating any other heartbeat-titled product as the same SKU.

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.
