which quarters are 100 silver

[MacOwen]

Hello! That's a great question about silver quarters.

When people talk about silver quarters, they are usually referring to the ones made by the U.S. Mint for general circulation in 1964 and earlier. These coins, which include the Washington, Standing Liberty, and Barber quarters, are not 100% silver. They have a composition of 90% silver and 10% copper. This alloy was used to make the coins more durable for everyday use.

However, the U.S. Mint has produced special collector's edition quarters that are very close to being 100% silver. Starting in 2019, the U.S. Mint began striking special Proof Silver quarters made of .999 fine silver, which is considered pure silver for investment purposes.

Additionally, the America the Beautiful series of quarters, released between 2010 and 2021, included a much larger 5 oz version also made from .999 fine silver. So, while you won't find a 100% silver quarter from historical circulation, these specific modern collector coins fit the description
