# pcgs-cert — PCGS certificate verification

Verifies PCGS coin/banknote cert numbers against `https://www.pcgs.com/cert/<cert>` (Firecrawl render of the
Cloudflare-challenged public Svelte page; Scrapfly fallback). One request per known cert.

- `certUrl(cert)` / `certFromUrl(url)` (also `/cert/verify?certno=`).
- Output: `catalog_item` (coin description, grade e.g. `AU58`, `identifiers.pcgs_number` + `pcgs_cert`, date/mintmark,
  denomination, mintage → `productionQuantity`, region, holder type, price-guide value in metadata, cert image) and a
  partial `population_report` ("Population" at grade + "Pop Higher"; `sourceUrl` = the linked public `/pop/pcgsnolookup` page).
- Fixtures: `data/fixtures/pcgs-cert/` — rebuild with `capture.ts pcgs-cert peace-dollar-1922s-au58=47044550 not-found=99999999`.
