Explore and catalogue British Empire coinage from the early 1700s onwards.

Colonial Coinage brings together centuries of numismatic history in one structured, reliable app for collectors. Whether you focus on British India, West Africa, the Caribbean, or early Canadian issues, the app provides a clear workspace for studying, identifying, and organising coins across the Empire’s former reach.

A collector’s workspace — Record every coin you own with photos, grades, and notes. View your holdings by territory, denomination, or period, and track your progress as your collection grows. Sort by rarity, year, or condition to see strengths, gaps, and emerging themes.

Connect with fellow collectors — Compare collections with friends on your own private leaderboard, or discover collectors who share similar interests. If you prefer to keep your collection to yourself, all social features can be turned off for a fully private experience.

Rich reference detail — Each coin type includes:
• Obverse and reverse descriptions
• Historical context and minting & issue data
• Rarity tiers from common to ultra rare
• Year ranges, composition, and key varieties

Clear layouts make identification straightforward, even for complex issues.

Personalised insights — Your collection generates several key metrics, including:
• Prestige Grade — weighted by rarity and condition
• Territory Star Rating — average grade of your best examples
• Completion Stats — see how close you are to completing a territory

Tap any metric for a plain-English explanation.

The Meridian Assistant — Choose a strategy — Prestige, Gaps, More Territories, Easy Wins, Missing Years, or Surprise Me — and Meridian highlights coins that suit your budget and your current collection. Suggestions are calm, data-driven, and collector-focused.

Colonial Coinage is more than a catalogue — it’s a dedicated workspace for studying, comparing, and enjoying three centuries of British Empire coinage.
