most of my characters in mains (https://toyhou.se/spierdolenie/characters/folder:1097421) are currently NFT/NFS. if you're interested in offering please check their profiles if they're open for trades/sale in "trade listing".  you may ask about other OCs of course, but it will be 99% no. their worth is also not updated regularly so it's possible it's higher than it is written at the time.
