What is an NFT’s rarity?

An NFT's rarity refers to how uncommon it is relative to other NFTs in the same collection. The concept of rarity is most commonly found in collectible or generative art-type NFT projects and is often used to determine the value of a specific NFT within a collection.

Where does NFT get an NFT’s rarity?

There are currently three sources NFT uses to get an NFT’s rarity:

  1. NFT’s own rarity scoring algorithm

  2. Rarity Sniper

  3. Creator’s official ranking

For more details on how NFT’s own rarity scoring algorithm works, please refer to the next question “How Does NFT calculate a collectible’s rarity?”.

Rarity Sniper is one of the most popular tools today for providing rarity scores on top NFT collections. Currently, Rarity Sniper supports rarity scoring for over 1,000 NFT collections across various blockchains, including Cronos, Ethereum, Polygon and Solana. If a collection available on the NFT marketplace is scored by Rarity Sniper, we will use the rankings provided by Rarity Sniper over the ones calculated by our own algorithm.

For certain collections on NFT, the official rankings are directly provided by the curated creators and applied to the relevant collections.

How does NFT calculate a collectible’s rarity?

When a ranking’s source is “”, this means that it is calculated by NFT’s own rarity scoring algorithm. An NFT collectible may have a specific set of properties (e.g. body, background, outfit, etc...). To calculate an NFT's overall rarity ranking within its collection, we use an algorithm that first calculates the rarity score for each of the properties the NFT holds. The fewer other NFTs within a collection holding a certain property, the higher its rarity score.

Once the rarity score of each property is calculated, these are summed up to determine the NFT’s overall rarity score.

Rarity ranks are then assigned to each NFT in a collection based on the descending order of their overall rarity scores. The higher an NFT's overall rarity score, the higher its position in the overall ranking.

Please note that the rarity ranks calculated by NFT’s internal system are not official rankings and may therefore differ from the rankings published officially by the collection’s own team. They may also differ from the rankings published across different NFT platforms and rarity ranking tools, since different statistical approaches may be adopted by different tools.

How do I find an NFT’s rarity rank?

For NFTs that are part of a collection eligible for rarity scoring, their rarity ranking is displayed directly on their card and NFT details page.

By hovering over the rarity rank chip, a tooltip will appear to indicate the source of the rarity score. In the following example, the source is NFT’s internal system.

In the following example, the source is Rarity Sniper.

In the following example, the source is a creator’s official ranking.

Why do some collections on NFT not have rarity scoring?

Some collections on the NFT platform may not have rarity scoring as not all collections support it. Rarity scoring is usually a concept which pertains to certain generative or collectible-based NFT collections where trait-level rarity is relevant.
