Even though collectors grabbed silver specimens for their collections, all are still valid currencies you can use in transactions. The US Mint produced these quarters of 90% silver from 1932 to 1965, while later pieces have come with cupronickel clad to copper composition. You can find two versions in circulation, the one made of silver weighing 0.20094 troy ounces (6.25 g) and clad type weighing 0.2 ounces (5.67 g). These coins with a reeded edge have a diameter of 0.95669 inches (24.3 mm). You can still find Washington quarters made after Laura Gardin Fraser and John Flanagan‘s designs in circulation. Since these new coins are typically inexpensive, you should look for older mintage when you want to add the most valuable quarters in circulation to your collection. The US Mint has struck 56 different quarters with different reverses from 2010 to 2021, but their obverse sides were always the same. The US Mint produced them from 1932 to 1998, but numerous coins are still used for transactions. Even though you can find several pricey and collectible American quarter types, only Washington quarters are still in circulation these days.
