Prices are computed in GBP. The selector converts the display value; the underlying transaction currency on cambridgetcg.com remains GBP.
No legacy wholesale price, derived channel value, image, or historical movement is published for this card. Stored CardRush-derived rows remain internal pending written and field-level source-rights records. TCGplayer is blocked and Cardmarket ingestion remains planned.
Authentication and bearer possession do not create source rights, so there is no signed-in history side door. Collector-authored bids and asks are separate market events and are not substituted here.
The canonical SKU is the federation-stable identifier — a partner with this SKU can resolve through /api/v1/universal/card/op-st09-009-ja for the mixed-rights math-mirror representation (aggregate NOASSERTION). Cross-source comparison and federation reverse-lookup are documented in the methodology.
