What is the 2021-S Silver Proof Quarter?
The 2021-S Silver Proof Quarter is part of the America the Beautiful Quarters and Washington Crossing the Delaware Quarter series produced by the U.S. Mint. Because they made it using 99.9% pure silver, the whole quarter was now worth so much more than regular quarters.

Silver proof quarters are distinct from regular circulating quarters since they are only produced for collecting with deep cameo contrast between frosted designs and mirror-like finishes.
