The mineral that can be scratched by glass but not a penny is calcite. Calcite has a hardness of 3 on the Mohs scale, which is lower than the hardness of glass (5.5) but higher than that of a penny (2.5).
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
The mineral that can be scratched by a penny is talc. Talc is the softest mineral on the Mohs scale, with a hardness of 1. A penny has a hardness of around 3.5 on the Mohs scale.
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
Calcite has a hardness level of 3 on the Mohs scale, which means it is relatively soft and can be easily scratched by harder minerals.

No, because calcite can be scratched off as easily as a copper penny. Would you like to have a diamond that breaks every time you do something active.

Diamond can scratch talc but is not scratched by calcite. Diamond is the hardest mineral on the Mohs scale, making it capable of scratching minerals with a lower hardness, like talc.
The mineral that can be scratched by a penny is talc. Talc is the softest mineral on the Mohs scale, with a hardness of 1. A penny has a hardness of around 3.5 on the Mohs scale.
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
Calcite has a hardness level of 3 on the Mohs scale, which means it is relatively soft and can be easily scratched by harder minerals.
