Copper solder for soldering copper?

My girlfriend was looking for a copper colored solder to solder copper to avoid the silver line of silver solder(sounds like some sort of tongue twister):). Someone from Ganoskin suggested using a pre-1981 penny(hammering it and drawing it out then cutting it into strips). From what I remember from school the difference between soldering, brazing, and welding is temperature and the intermixing of metals. My first question is has anybody heard of such a solution for soldering copper? If so, how is it possible to solder a metal with the same metal? Wouldn't the temperature to melt one be the same to melt the other, making this welding? If this is actually soldering, can someone please explain the difference between soldering, brazing, and welding? Normally I probably wouldn't give this a second though, but usually the information from Ganoskin is pretty good.
