It's 1985 that they switched. When I was a kid we used to collect the 1985 and older pennies and take a blow torch to them. All copper pennies would turn into a ball of liquid copper. The newer ones would just bake.

Thank you for the comment! I went ahead and checked up on this because I wasn't 100% sure. Now I am. I checked the U.S mint site and they stated in a bullet:
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.
