I'm not suggesting you shouldn't do anything with your leftover coins if you want to go that route. I think it's best to do the rookie premiere sets first to get the 15 tokens, and then sell whatever you have left for MHC, NBA 2K, Schrute Bucks, etc. MHC has lost a bunch of value and EA has seemed to begin banning people easier, so the 3 auctionable 23 players seems safer.
