How much is a sphinx?

Excuse me, but I'm a bit confused by your question. Are you referring to the mythical creature, the Sphinx, from ancient Egyptian mythology? If so, it's worth noting that the Sphinx is not a tangible object that can be bought or sold, so there isn't a specific monetary value associated with it. However, if you're asking about a specific sculpture, statue, or representation of the Sphinx that's available for purchase, the value would depend on several factors such as the artist, the materials used, the size and intricacy of the piece, and the current market demand. For example, a small, mass-produced Sphinx figurine made of plastic or resin might only cost a few dollars, whereas a large, hand-carved Sphinx statue made of marble or granite by a renowned artist could be worth tens of thousands or even millions of dollars. So, could you please clarify which Sphinx you're referring to, and perhaps provide some additional context to help me give you a more accurate answer?
