In Chemistry... when comparing Zinc and Iron what are the physical differences?

I had a lab this past thursday where we had to find the density and specific heat of an UNKNOWN metal. My SH and D were both CLOSE to both Zinc and Iron. My metal looked like a light gray substance and it looked like it had at one point been melted and dropped into small hershey kiss shapes. Can anyone tell me some physical characteristics that would deem it one or the other. Thanks.
