Answered by John
Use the penny to determine its hardness.
Answered by Hal
The penny to compare the hardness. The hand lens for hardness and luster. The tile to rub it on to get a powder streak for color. The hammer to break it to identify fractures. The pocket knife to see if it is brittle, flexible, or elastic.
