I have a tiffany's sterling silver money clip. I don't have much problems with tarnishing if at all. I did at the beginning when I used to put my leather card case and the money clip in the same pocket though. Now I know that exposure to leather causes tarnish. Just google and you will see what aides in tarnishing. To me, leather, esp with magnets, stainless steel looks cheap but if you find one that looks elegant, all the more power to you.
