Bacteria hop from hand to hand aboard dollar bill

RE “$1 bill: Time for change” (Editorial, Dec. 10): Not only is the need to reprint US $1 banknotes a drag on the economy, but the grimy dollar bill is also a health risk. The number of bacteria that this heavily used paper currency carries from hand to hand can be stupendous. The dollar coin offers a safer alternative.

While we are talking about a rational change in the US currency system, what about the copper penny? Let’s get rid of it, too.
