Copper is not unhealthy, it is required for healthy body functioning. Wikipedia describes copper deficiency nicely:

That said, like zinc, copper is unhealthy in very high doses.
Both copper and zinc are required by the human body but they interfere with one another, especially in absorption (they seem to use the same transport system to cross out of the gut into the blood stream). Too much zinc can cause copper deficiency, which is why many zinc supplements have added on copper.
