what coins are silver us

[DiKathryn]

Well, if you're hoping to find treasure in your couch cushions, you'll need to know which coins have that silvery shine. The golden rule, or perhaps the silver rule, is to check the date. Most U.S. dimes, quarters, half dollars, and dollar coins minted in 1964 or earlier are the real deal, containing a whopping 90% silver.

This category, often called "junk silver" (which is a terrible name for something so valuable), includes a whole cast of characters. You've got your Roosevelt and Mercury dimes, Washington and Standing Liberty quarters, and Kennedy, Franklin, and Walking Liberty half dollars. Even the hefty Morgan and Peace dollars are part of this 90% silver club.

The government, however, likes to keep us on our toes. After 1964, the silver content took a nosedive. Kennedy half dollars minted between 1965 and 1970 contain only 40% silver. Some Eisenhower dollars from the 1970s also got the 40% silver treatment. And for a real plot twist, let's not forget the humble nickel! During World War II, from 1942 to 1945, nickels were made with 35% silver to conserve nickel for the war effort.

So, the next time you get some change, give those dates a second look. Anything from 1964 or earlier is likely more than just pocket change.
