It's quite extraordinary to find dimes and quarters worth millions.
Rare coins can indeed fetch high prices in the collector's market, especially if they're in exceptional condition or have historical significance.
For instance, rare dimes could include the 1894-S Barber Dime or the 1916-D Mercury Dime, among others.
As for the bicentennial quarter, if it's truly rare and in pristine condition, it might be referring to the 1976 Bicentennial Quarter with the drummer boy design.
it's essential to verify the authenticity and rarity of such coins through reputable numismatic experts or organizations.
While valuable coins do exist, claiming astronomical sums without proper authentication could lead to disappointment.
