While rare coins can indeed fetch high prices at auctions, it's quite unusual for a single coin to be valued at such exorbitant amounts.
It's important to verify such claims with reputable sources or numismatic experts.
In the case of a Bicentennial Quarter (dated 1976), while there are some valuable varieties, such as those with errors or minting anomalies, it's unlikely that any single quarter would be valued at $80 million or even $20 million USD.
However, even the rarest and most sought-after coins usually don't reach such astronomical values.
If you're interested in coin collecting or investing, it's always a good idea to do thorough research and consult with experts to ensure you're making informed decisions.
