I'd like to suggest these for coins.

Mostly making this post to start the thread and take this down for my future reference.

ohh brass, that would be cool. Personally I'd rather it be a little easier to acquire. One option would be to make a standardized "size" and color for each level of currency then have a metal associated with it. The standard D&D gold, sliver, bronze comes to mind be we can always use different levels.

found some how-to here:
