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.

Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
Which is heaver a 2006 penny or a 1982 penny?
A 1982 penny is heavier than a 2006 penny. In 1982, the composition of the penny changed from being mostly copper to mostly zinc. The higher copper content in the 1982 penny makes it heavier than the 2006 penny, which is mostly zinc.

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.
Describe how to distinguish between a mineral with a hardness of 6 and one with a hardness of 4 using only a glass plate and a copper penny?
To distinguish between a mineral with a hardness of 6 and one with a hardness of 4, you can use the glass plate and the copper penny for comparison. First, scratch the mineral against the glass plate; if it scratches the glass, it has a hardness greater than 5. Then, use the copper penny to scratch the mineral; if the mineral scratches the penny, it has a hardness greater than 3. If it scratches the glass but not the penny, it has a hardness of 6; if it scratches the penny but not the glass, it has a hardness of 4.
What is 1977 zinc penny worth?
