On one sized of the coin there is a lady standing. It looks like she has a hammer in her hand, pointing at a round item. In the background there is a volcano. The size that has an eagle with it`s wings wide open,  is standing on a crest. The crest has a lion on it and a ribbon under it.

Right now I have no way of sending a photo.
