As on Wikipedia and several other Wikia project, in order for an article to become featured, it must be nominated as a good article before it can advance. Good articles on Currency Wiki are expected to be plentiful, and will most likely be added within the next few months. However, before good articles can be added, a proper image must be used to symbolize one.
For the symbol, I decided upon the design of the obverse of the Swiss 2 centime coin, which features a plus, just as Wikipedia's symbol () does. I was originally going to search for an image of a coin with a silver or bronze-colored star on it, but after recognizing by possession of this coin, decided to use it for good articles.
