Rarity

Rarity refers to how uncommon or infrequent something is within a given set or population. Items or features that are rare appear less often, making them more unique or valuable. For example, a rare coin might be one produced in limited quantities, or a rare animal species has a small number of individuals left. Rarity is an important concept in various fields like collectibles, ecology, and economics because it influences desirability, price, and significance. Essentially, the rarer something is, the more distinctive it tends to be.
