First Silver Found In Circulation

I have checked my change and been having everyone one else in my family check their change for about 3 years now. After about a year or two of checking I came to a realization that I probably will never find silver in circulation because they are so scarce, but I still checked my change just in case. So, my brother dumped 2 quarters, 2 Pennies, and a dime in change on the floor, from a purchase he made. I glanced at them, then I took a closer look at the dime because it was all worn. I looked at the year and it was 1962 ! My brother didnt care so I asked if I could buy it from him for $1.10 and he said sure. I still can't believe it, my first silver find!
