How much did Sonic sell for?

Excuse me, could you please clarify for me the specific context in which you're asking about the sale price of Sonic? Are you referring to the video game character Sonic the Hedgehog, or perhaps a different entity entirely that goes by the name of Sonic? Additionally, if you're inquiring about a financial transaction involving Sonic, could you provide some more details, such as the date of the sale, the platform on which it took place, or any other relevant information that would help me give you an accurate answer? Without this information, it's difficult for me to provide a precise response to your question.
