Why are 2004 quarters worth $2,000?

Could you please explain why quarters minted in the year 2004 are being valued at an astonishing amount of $2,000? Are there any unique or rare qualities about these quarters that set them apart from other years? Is it a result of a limited mintage or a special design feature? Is there a growing collector's market for these specific quarters, driving up their value? I'm intrigued to understand the reasoning behind this high valuation and how it came to be.
