I saw this posted on another website I'm on... It keeps me hunting...
4,233,725 40% silver Kennedy half dollars (1965 - 1969) would still be left in circulation if 99.5% of them have already been found and/or melted.
Four million, two hundred and thirty-three thousand, seven hundred and twenty five.
So when someone tells me "why are you searching for silver halves when 99.5% of them have been found/melted already," I'll say "great, then there are still 4.2 million left for me to find."
