Background

Steam Siege is the English Pokémon TCG sealed booster box filed on CARDZ under set code STS. Language reads as English from the ptcg-en stamp. The official name is Steam Siege; STS is the three-letter filing stamp, not a product nickname.

Official filing keeps the standard booster-box SKU. Game is ptcg, group is ptcg-en. This packet has no population, sale print, or reference quote.

Rank 115 is board position only. Keep the English STS box identity. A Japanese printing or another short English set code is a different row.

Desk check starts with Steam Siege plus STS, then English language. Do not merge this line with another English set code or a Japanese case.

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.
