The Mfers by NFT Influencer Sartoshi are a collection of 10021 stick man collectibles. Although initially (Nov 30, 2021) they were cheap to mint (0.069E), they quickly exploded into something huge. All 10,000 items were minted in less than 10 minutes. The floor price soared from 0.3E to close to 6E, then fell back and stayed at around 3E for a long time. Hoodie mfers are not rare mfers, but they are very popular with investors due to their unique appearance and classic punk properties. The highest transaction was mfer#904 which was sold for 80E ($160,000 as of Apr. 2023).
