Among them are the iconic bicentennial quarters, minted in 1976 to commemorate America's 200th anniversary.

Proof coins are struck with meticulous care, intended for collectors and investors.
Among the five newfound treasures, one stands out for its extraordinary condition—a specimen so pristine that it defies belief.
Another of the five quarters possesses a striking minting error, rendering it a true anomaly.
