cards — master identity index

108,522 card identities · 1909–1980 · baseball only

What this dataset is

The master identity index for every routable card on rawcomps.com. Each entry is keyed by the composite natural key from ADR-003: (sport, year, set_code, card_number, variation). This is the spine the entire site sits on — comp_v2, walker_comps, and the per-card detail pages all join back to this index by card_id.
