Yes, I remember these interesting treasures still circulating in the 1960s. I always check my change, and found one a couple of years ago. But they are probably going to become a once-in-a-lifetime find, in pocket-change, for those searching, soon. One can find them at a Local Coin Shop. Every once in a while, an extra fine, or better will pop up, for a $1.25 (melt value). About 18 will exceed one Troy Ounce. Thanks again, @trumpman.
