I heard on NPR the other day that "they are" ceasing production of the penny in April? Prolly not correct. Yet when is it gonna happen? http://www.npr.org/2015/11/26/457397908/critics-wonder-whether-pennies-make-sense-anymore http://www.moneycrashers.com/get-rid-penny-reasons/ https://en.wikipedia.org/wiki/Penny_debate_in_the_United_States I like the copper zinc combo to make Voltaic piles. https://en.wikipedia.org/wiki/Penny_battery So I just ordered 8 box's. Plus I'm doing my floors in the zinc clads.
