What penny is worth $1,000,000 today?

Could you please clarify, are you referring to a specific type of penny or is this a hypothetical question about the potential value of a penny in the future? If it's the latter, it's important to note that the value of a penny is largely determined by market forces and economic conditions. However, if you're asking about a rare or unique penny that is currently valued at $1,000,000, I would be surprised to hear of such a high valuation for a penny, as they are typically not considered valuable collectors' items to that extent. Is there a particular penny you have in mind or are you simply curious about the concept?
