What nickel is worth $10000?

Excuse me, but I'm a bit confused by the statement "What nickel is worth $10000?" Could you please clarify what you mean by that? As far as I'm aware, a nickel, which is a type of coin in many currencies, is typically worth a very small fraction of a dollar. Are you perhaps referring to a rare or collectible nickel that has a high value due to its rarity or condition? Or is there another context in which you're asking about the worth of a nickel? If you could provide more information, I'd be happy to try to answer your question more accurately.
