Indian Head 1864 -Copper-Nickel or Bronze?

I am looking at a raw 1864 Indian Head that an oldtime collector has, it has beautiful toning and I can purchase it at a reasonable price regardless of variety. How can I tell which variety it is?
Thanks,
Dan

Bronze have a darker appearance.
the toning makes the color difference hard to spot but the weight and thickness will help a lot
CN=4.87 grams Bronze=3.11 grams
