Collectibles generally are objects that are collected by connoisseurs. For example, items of art, stamps, coins, cars, wines, antiques, etc.
In the crypto world, there is a similar term: crypto-collectible. This is a cryptographically rare, non-fungible digital property or NFT. Unlike cryptocurrencies that require all tokens to be similar, each crypto-collectible NFT token is exclusive in amount or distinct. Crypto-collectibles can be a copy of real-life objects like pictures, songs, patents, etc.
