The easiest way to do this, I think, would be to define class Currency, with subclasses (or perhaps instances) SilverPiece, GoldPiece, and so on. There's lots of info floating around on handling multiple real-world currencies; you should be able to do D&D money the same way. > > I was going to add some options to where if it was set to something > below 0 that it would automatically subtract 1 from the one above it, > add 10 to itself, and continue doing the math while repeating if > necessary with recursion.

Use the power of a decent object model.
