Copper Rock Hammer

These are website-defined tiers for scores out of 10, rather than official manufacturer categories.

1–2 Common · 3–4 Uncommon · 5–6 Rare · 7–8 Ultra Rare · 9 Mythic · 10 Legendary.

Legendary is the highest released rarity tier. The ∞ symbol identifies a separate Unreleased or One-off status; both may apply. It is not a numeric score or a higher rarity rank. While a special status applies, the numeric score is hidden and retained internally for restoration.

Not yet assessed means no rarity assessment is recorded; it does not mean a score of zero.
