The claim that two rare dollars and a rare Bicentennial Quarter, each valued at $15 million, are still in circulation is highly unlikely and would be extraordinary if true.
While there are indeed rare coins that can fetch high prices among collectors, valuations in the millions for coins in circulation are virtually unheard of.
Dollars and quarters, including Bicentennial Quarters, are commonly found in circulation, and while there may be some rare variants or minting errors that increase their value, valuations in the millions for individual coins, especially those in regular circulation, are exceedingly rare.
if such coins were genuinely worth $15 million each, it's highly improbable they would remain unnoticed in circulation given the attention and scrutiny that rare coins receive from collectors, enthusiasts, and professional numismatists.
If you believe you have rare coins that may be valuable, it's essential to have them evaluated by a professional numismatist or coin dealer to determine their true value.
They can assess factors such as rarity, condition, and demand among collectors to provide an accurate valuation.
