I know it sounds stupid, but I really do need to know. And can you give me a source so I can check several places?

See 3.1 Sample Preparations in this PDF file. Copper seems to have an index of refraction of 0.249 + 3.41i at λ = 633 nm.
Addendum: Thin deposited copper can be transparent.

Refractive index is a ratio of speeds of light in different media. It seems pointless to talk about speed of light in copper, but there is still a refractive index. It can be found by Brewster's Law. In short, light reflected off surfaces is partially polarized. The degree of polarization increases as the angle between the light and the surface reaches 0. The angle at which complete polarization occurs tells you the refractive index of the material.

CRC handbook may come in handy. You could try in there
