Hey there! That's a great question, and it's always fun to look for treasure in your pocket change. Based on the information provided, the key to a U.S. coin having silver value is almost always its mint date.
A good rule of thumb is that most U.S. dimes, quarters, half dollars, and dollar coins made in 1964 or earlier are 90% silver. This includes a lot of different coins, such as and Peace dollars, Washington quarters, Franklin half dollars, and Mercury dimes. If you find any of these coins with a date of 1964 or an earlier year, it's worth more than its face value because of the silver it contains.
There are a couple of notable exceptions to keep an eye out for as well. Kennedy half dollars that were minted between 1965 and 1970 aren't 90% silver, but they are still valuable as they contain 40% silver. Another special case is the "War Nickel." Jefferson nickels made between 1942 and 1945 contain 35% silver. You can easily spot these because they have a large mint mark (P, D, or S) on the back, right above Monticello.
So, when you're checking your coins, the date is the most important thing to look for! The actual melt value of these coins will fluctuate with the daily market price of silver.
