I recall someone using rhodium, but I'm not sure about that. I thought rhodium was just a coating? I prefer the antiqued brass and silver coins, though some look better when polished.

Just be careful when doing your coin. Some metals look almost the same and are very hard to tell apart. For instance, bronze and gold, nickel and silver. You can only tell them apart when you hold 1 of each metal next to each other.

I personally believe that Black Nickel can make an extremely attractive coin if done correctly. A prime example is the San Diego coin, which I think is one of the best designed coins seen so far. However, the one drawback of Black Nickel is that it's very easily scratched and dinged if not protected immediately.

I agree. Than San Diego coin looks very well done.

 

As for Black Nickel, from what I have seen, the best Black Nickel coins are those where you have most of the coin color fill.
