St. Pete-based Autographia to auction Elon Musk signed Tesla and matching NFT


    St. Pete-based Autographia, a provider of authentic autographed memorabilia, will sell non-fungible token (NFT) matches for some of its inventory.

    The opposite of fungible assets, like dollars, which can be swapped evenly for each other, NFTs are one-of-a-kind and represent digital rarity.
