US and Canadian pennies (cents) are actually 97% zincwith a thin plating of copper. The zinc has a Moh's hardness of 3 and the copper a Moh's hardness of 2.5. The Moh's scale runs up to 10, with most minerals being harder than 3. The only significant minerals lower than 3 are gypsum, alabaster and graphite. Most common minerals range from 6 - 8 on this scale.

What can talc scratch?
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
How Which property might you test by rubbing one minerals directly against another and?
You can test the hardness of minerals by rubbing one mineral against another. This method helps determine which mineral is harder based on whether it scratches the other. The Mohs scale of mineral hardness is often used to classify minerals based on their ability to scratch one another. For example, if a mineral can scratch a known mineral like talc (hardness 1), it is likely harder than talc.
