Question

I need them for a science project thats worth a lot of points and i cant change my project.

Answer 1

They are what ever they want them to be. The content changes whenever they have a problem getting a particular alloy. They are also pretty closed mouth about what the alloying ingredients are to prevent counterfieting. The most common ingredients are : Ni, iron, and aluminum.

Ni is listed as a stragetic material ( one that the USA can't get along without) and whenever there is a war or police action, there is a restriction on it's use. They start using low Ni alloys  for the coinage.

For most of its history (since 1938), the Jefferson nickel has contained 75% Cu and 25% Ni.
