[ExI] Why is this still a thing?

[Dylan Distasio]

That might have been true pre-1982 but they're mostly zinc now:

That made the metal composition of the cent*95 percent* copper and *5
percent* zinc. The alloy remained *95 percent* copper and *5 percent* zinc
until 1982, when the composition was changed to *97.5 percent*zinc and *2.5
percent* copper (copper-plated zinc). Cents of both compositions appeared
in that year.
