- Multiple issue variants per type (year, mint mark, type)

Features
Intelligent Coin Matching
Fuzzy search with denomination normalization, issuer resolution, and non-Gregorian year support (Meiji, Hijri, Thai Buddhist calendars).
Granular Data Control
Choose exactly what data to sync: Basic catalog info, Issue variants, or Pricing data. Update only the fields you want.
Visual Field Comparison
Side-by-side comparison of existing vs. new data. Cherry-pick individual fields to update or accept all changes at once.

Multi-Machine Sync (Supporter Edition)
Share API cache and settings across multiple computers via a shared network drive, Dropbox, or NAS. API call counts accumulate correctly across all machines. One-click settings import on new machines.
