The problem

A collector of pioneer and territorial US gold coins (1830s-1840s, $10k-$2M range) wanted a robust system for identifying coins, finding their value, and monitoring dealer websites for acquisition targets. The market operates on relationships and scattered auction data. Few dealers specialize.

What we built

  • Dealer intelligence report covering 10+ specialty dealers, key contacts, professional memberships, and Twitter handles
  • Curated source list with target search keywords (Territorial, California gold, California fractional gold, Pioneer gold, Colorado gold, slug)
  • Next.js + Supabase + Vercel app scaffolding for the coin tracking system
  • Live workshop demo of building scraper agents, monitoring dealer sites, and the broader Claude Code workflow
