Which quarter is worth $1,000,000 today?

Could you please elaborate on the context of the question, "Which quarter is worth $1,000,000 today?" Are you referring to a specific type of investment or asset that is commonly known as a "quarter" in the cryptocurrency or finance world? Typically, quarters are associated with coins of lower denominations in currency systems, not high-value investments. Are you perhaps alluding to a unique, rare, or specially minted coin that has appreciated significantly in value? Or is there a misunderstanding in terminology, and you're referring to a different type of investment that has recently reached that milestone? Clarifying these details would help provide a more accurate and informative response.
