Estados Unidos Type 6 20 Cents: Who Owns What
How often each Estados Unidos Type 6 20 Cents coin actually turns up in a collection, measured by how many of the 158 collectors of this set have one. Coins are graded from Common to Extremely scarce against the set's most-owned coin — a measure of collecting frequency, not of how many survive.
Hardest to find in real collections

About these numbers
Ownership counts come from the same live per-coin counters shown across the LuckyCoin catalog; set-level collector counts come from the annual full-collection scan behind The State of Coin Collecting 2026. Counts are collector-reported and aggregate-only. Scarcity tiers come from 100 × (1 − owners ÷ owners of the set's most-owned coin): Common under 25, Uncommon 25–49, Scarce 50–74, Very scarce 75–89, Extremely scarce 90+. This reflects how often a coin is collected, not its surviving population — it is not the Sheldon rarity scale. CC BY 4.0 with attribution.
