While it's certainly exciting to imagine stumbling upon rare and valuable coins in everyday circulation, the claim that eight rare dimes and a rare bicentennial quarter worth $22 million each are still in circulation should be approached with skepticism.
Extreme Rarity: Coins worth millions of dollars are typically rare numismatic treasures that are highly sought after by collectors and investors.
The likelihood of multiple coins of such extreme rarity and value circulating freely in the public domain is exceedingly low.
Numismatic Knowledge: Knowledgeable collectors actively search for rare coins, including dimes and bicentennial quarters, in circulation and at coin shows, auctions, and estate sales.
If such valuable coins were indeed in circulation, it's highly probable that they would have been discovered and removed from circulation long ago.
Authentication and Grading: Rare coins of significant value are often authenticated and graded by reputable third-party grading services to verify their authenticity, condition, and provenance.
Mint Errors and Varieties: While there are certainly valuable and rare varieties and mint errors in the world of numismatics, their occurrence in circulation is relatively rare.
Coins worth millions of dollars typically result from unique circumstances, such as rare die varieties, minting errors, or historical significance.
