01 / The problem

What made this hard

Numismatics is an older, more conservative market than trading cards, and the audience is rightly sceptical of anything automated. Removing every barrier — no account, no card, no cost — was the way in, which meant the economics had to work without a paywall on the core action.

02 / What we did

Four things,
on every project.

  1. Marketing site and conversion path

    The free estimate is the hero, not a secondary CTA. Everything on the page moves toward a first upload, and the value capture lives downstream in exports, history and collection features rather than in front of the thing people came for.

  2. SEO, AEO and GEO

    Aimed at the coin-and-condition long tail plus the service comparison queries — PCGS against NGC against PSA — where a tool that estimates all three at once is the natural answer. Marked up so assistants can cite it.

  3. Product build

    Photo intake, simultaneous estimates against three grading standards with per-estimate confidence scores, condition analysis, a submit-or-hold recommendation, and PDF and CSV export for people keeping records outside the app.

  4. Backend and hosting

    Anonymous-first session handling so results survive without an account, inference serving, export generation, rate limiting to keep a free tier viable, and the hosting and monitoring stack.
