I don't know - are there more medals to be had? I know that some get replaced as you play more games. I guess I could try for a 1st place medal, but the way I play that hardly seems likely, of course, once you get that it could be replaced by a former 1st place medal.
I read the medals go up to 1000 games so keep playing Weyr.
(BTW I doubt any of us will live THAT long
