Asked by Aline
Another question on the subject of coins. We have to evaluate another group's metal choices. My friends' group chose gold for the outer layer and zinc inside. Why is zinc a good choice? I know it's relatively inexpensive, but it's soft. Why would someone choose zinc? Thank you again.

I think that the probably reason is the low cost of Zn. Au, you know, is soft, also.
