From part of an email from Poppa G:
“…how about getting some half-dollar pieces back into circulation? I haven’t seen a half dollar in many years, and I sometimes ask cashiers if they ever see one and the answer is no. It would be a very useful coin, although vending machines might have to be rejiggered to accept them. I’d say the priorities are 1) reintroduction of half dollar, 2) world peace.”
