In [[1505]] Copernicus returned to [[Frauenburg]] in [[Ermland]], [[Prussia]], since 1945 a part of [[Poland]] where he served as canon and was involved in diplomatic negotiations between the Poles, the [[Teutonic Knights]] of Prussia and [[Ermland]], Prussia.  Around that time, he came up with the notion that the appearance of debased currency drives good coins into hiding ( see [[Gresham's law]]). [http://www.rit.edu/~flwstv/copernicus.html]
