King Philip II of the northern Greek area called Macedonia was Alexander the Great's father. Alexander was educated by Aristotle. I have a bronze coin struck during Philip's reign in my coin collection.
I was fortunate enough to buy a second coin from him at the El Paso coin show last week. I gave it to a friend who is doing a fantastic job of showing it around to non-coin collectors.
This is a link to a site on the web that has zillions of pictures of coins by Phillip II:
Both of these two coins are both made of bronze. Bronze is a copper and tin alloy: http://en.wikipedia.org/wiki/Bronze
