Hey, Diggin Dave in Dixon.....Love the SILVER 1943 Mercury Dime with good strong details....one of my favorite coins to find.....Live in Florida now, but born amd raised in Knox County area, but I have hunted many city parks in many of the smaller towns in Illinois while living there for over 45 years......I loved digging in the good black earth there.....just saying. HAPPY HUNTING everyone & GOOD LUCK.
