I found this penny in my change googled it and I unfortunately dont have a scale to be able to weigh it to know if its indeed copper or not how else can i test it to find out?
You could invest in a pocket jewelry scale with a .01 gram resolution for about $10 - $20. Handy to have for coin collecting.
It's kind of a moot point, since as @paddyman98 mentioned, it's not going to be worth very much either way. Unless you just want to know.
