What is an NFT rarity ranking and How does it factor into the value of an NFT?

NFT rarity rankings are a metric that quantifies the uniqueness of a non-fungible token’s (NFT’s) traits as compared to other NFTs within the same collection.

Every NFT is unique, a combination of different traits of differing rarity – ranging from common features that appear in thousands of a collection’s NFTs to one-of-one traits that only appear a single time.

How are NFT rarity rankings calculated?

There are many ways to calculate an NFT’s rarity, each of which will result in a different score. 

Some methodologies determine overall rarity by taking the average rarity of each trait expressed within an NFT. Other methods consider only the rarest trait, ignoring the scarcity of all other traits. Some multiply the rarity values of all the traits shown within an NFT by each other.
