Singles cost baseline by collection goal
A master set has no useful cost until its scope is defined. These totals add one current TCGplayer US market quote for every item in each checklist definition; they are a dated singles baseline, not a guaranteed checkout total or collection appraisal.

Snapshot date: 2026-09-21. Totals exclude shipping, tax, seller availability and condition adjustments. A preferred regular variant is used for the numbered and collector definitions; the treatment definition counts each sourced market identity separately.
TCGOdds does not currently label booster boxes “better value” for Steam Siege. A fair box-versus-singles comparison also needs a timestamped sealed-box price and enough sourced opening evidence to describe expected contents. Until both inputs exist, use the interactive Steam Siege checklist to price your actual missing cards instead.
Data boundaries and sources
Catalog identity comes from the pinned TCGdex dataset and TCGCSV product records; USD market observations come from TCGCSV's TCGplayer feed. Selected chase cards have evidence-rich detail pages, while the full catalog remains in the checklist. Images stay reduced 200px identifiers; no high-resolution downloads are distributed.
