Can you sell Sepolia ETH?

Excuse me, could you possibly clarify something for me? I've come across the term 'Sepolia ETH' and I'm wondering if it's something that can actually be sold. Is Sepolia ETH a specific type of Ethereum token or asset that can be traded on cryptocurrency exchanges? If so, could you provide me with some more information on how to go about selling it? I'm new to this space and would appreciate any guidance you can offer.
