Mintage & Rarity Scale Lookup
Enter an estimated surviving population to see its tier on the R-1 to R-8 Rarity Scale — add the original mintage for an estimated survival rate.
Rarity scale (R-1 to R-8)
An estimated 31 to 75 examples are known to survive.
Scarcity is about today, not the mint report
Two coins with wildly different mintages can end up equally rare if one was hoarded by collectors and the other was spent into oblivion. The Rarity Scale sidesteps the mintage figure entirely and classifies a coin by what actually survives, which is the number that matters to anyone trying to find one today.
Treat any surviving-population estimate as exactly that — an estimate, refined over time as more examples are documented or as previously unknown ones turn up.
Frequently Asked Questions
Why isn't rarity just based on the original mintage?
Mintage tells you how many were struck, not how many survive. Coins struck by the million can be melted, spent, or lost until only a handful remain, while a smaller mintage that collectors saved from day one can survive almost intact. Rarity is a statement about today's known population, not the mint's original production run.
What is the R-1 to R-8 Rarity Scale?
It's a commonly used numismatic scale that classifies a coin by its estimated surviving population: R-1 (more than 1,250 known) is Common, down through R-4 (Very Scarce), R-6 (Very Rare), and R-8 (Unique or Nearly Unique, 1 to 3 known). It complements the Sheldon grading scale but measures a different thing — scarcity, not condition.
Where do surviving-population estimates come from?
Serious estimates come from auction records, population reports published by grading services, specialist reference books, and census projects that track individually known examples over years. This tool doesn't estimate that number for you — it classifies whatever estimate you already have.
Does a rare coin cost more?
This tool doesn't cover pricing. Rarity is one factor among several — including condition, demand, and historical interest — that collectors weigh, but this site does not publish valuations or price guidance of any kind.
