What can a copper penny scratch?
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
Can quartz scratch a copper penny?
No, quartz is harder than copper and can scratch it. However, a copper penny is typically made of a copper-zinc alloy that is harder than pure copper, so it might be more resistant to scratching by quartz but it is still possible.
Is copper ferromagnetic?

Is calcite a copper?
No it is not.
Is calcite harder than copper?
Yes, calcite is softer than copper. Calcite has a Mohs hardness of 3, while copper has a Mohs hardness of 2.5 to 3.
Will quartz scratch a peice of copper?
Yes, quartz is harder than copper on the Mohs scale, so quartz can scratch copper.

What minerals can be scratched with a copper coin?
Oh, dude, like, a copper coin can totally scratch minerals with a hardness of 3 or lower on the Mohs scale. So, you know, minerals like calcite, gypsum, and talc better watch out for that shiny penny! But, like, don't go around scratching random rocks with your spare change, okay?
Can quartz scratch a copper penny?
No, quartz is harder than copper and can scratch it. However, a copper penny is typically made of a copper-zinc alloy that is harder than pure copper, so it might be more resistant to scratching by quartz but it is still possible.
What mineral can be scratched by a steel knife but not a copper penny?
Copper. Copper has a hardness of 2.5-3 on the Mohs scale, while a steel knife generally has a hardness of around 5.5 - 6.5. This means that a steel knife can scratch copper, but a copper penny cannot scratch a steel knife.
What mineral do you scratch with a penny or steel wool for hardness?
Copper and steel have hardness of around 3 and 6 respectively on the Mohs scale. You can use them to test any mineral, and roughly estimate its hardness. If it's scratched by copper, it's less than 3, if it's scratched by steel but not by copper, it's between 3 and 6, if neither copper nor steel scratches it, then it's above 6.
Can you scratch a copper coin with a knife blade?
Yes, it is possible to scratch a copper coin with a knife blade as copper is a relatively soft metal compared to steel. However, the knife blade needs to have a harder material rating in order to scratch the copper.
