Why I built it

A practical problem turned into a working project.

I wanted a faster way to identify coins, estimate melt value, track inventory, and make better decisions at home or during an auction.

What it does

  • Live metals pricing with a server-side cache and fallback states
  • Melt calculations for common silver coin types
  • Coin and paper-currency reference views
  • Browser-local inventory tracking and auction calculations
