Celebrate the practical nurse in your life, more commonly referred to as an LPN, or licensed practical nurse! This is an older sterling silver charm by the R.L. Griffith Company, shuttered in 1982, so the charm is at least 39 years old. It is in excellent condition & measures 1/2-inch in diameter & would hang just about 3/4 of an inch, as shown in photos 4-5. Slightly smaller than a U.S. dime, photo 6. I have 2 available in same condition, shown in last 2 photos, you will receive one of them!
