Fictional Currency: Lion, used by the American Wizarding Confederation
Proposed Symbols for Fictional Currencies : American Wizarding Confederation Lion
In the Alexandra Quick series of Harry Potter fanfic stories, the American monetary unit is the Lion. I thought "how would magicians symbolize a lion... oh, right." The dot, borrowed from the alchemical symbol for gold, seems like a good parallel to the crossing lines so common in Muggle currency symbols.
