== Category reversion... == 

 That is fine, but it wasn't a request.  The category I replaced is about to be deleted after a discussion on WP:CFD.  I'm one of the closing admins there so I don't normally take part in the discussions to rename categories and such.  At the moment, when that category is deleted the article you reverted will have a redlink to the category. 

 Because the coin is still in use, perhaps you would like to place it in Category:Currencies of the Eurozone or Category:Currencies of Europe?  Thats are more of the renamed categories in this group of changes.  If neither of those fits, you could probably ask at Wikipedia:WikiProject Numismatics for a relevant category.  Thanks!
