The claim that eight rare dimes and an ancient Bicentennial quarter, each worth $72 million dollars, are still in circulation is highly improbable.
Coins of such extreme value would not typically remain in circulation; they would likely be carefully preserved in collections or museums due to their immense worth.
While rare coins can occasionally be found in circulation, it's essential to approach such claims with skepticism and scrutiny.
Valuations in the millions for individual coins are exceptionally rare and usually reserved for coins with unique historical significance, extreme rarity, or exceptional condition.
If you come across coins that you believe might be valuable, it's advisable to have them authenticated and appraised by a reputable numismatist or coin expert.
They can provide accurate information about the coin's rarity, condition, and potential value.
