Which quarter is worth $1,000,000 in US dollars?

Excuse me, could you please clarify something for me? I'm intrigued by the statement that a certain quarter is worth an astonishing $1,000,000 in US dollars. Could you elaborate on which specific quarter you're referring to? Is it a rare coin, perhaps, or a unique token from a particular era or country? I'm genuinely curious about how such a seemingly ordinary denomination could hold such extraordinary value. Could you enlighten me on the background and reasons behind this extraordinary claim?
