Germania is an ancient name for Germany used by the Romans. So, there is a meaning behind the name.
A silver round is like a coin, except it has no status as legal tender. The Germania took some time to research, because the Germania silver round has a denomination on it. It clearly claims to be five marks. This could prove a problem in the future. Currently, the currency of Germany is the euro, so there is no problem using the mark as a historical reference without indicating the Germania is currency. However, with the United Kingdom poised to finish existing the European Union, and the economic stress imposed on the European Union by several members, should there be a collapse of the European Union the former currencies of Europe could be revived. This could then become a problem for the Germania.
