I would have to go with these babies: Swiss Bank Corporation Kilo Silver Bar Metaux Precieux Kilo Silver Bar UBS Kilo Silver Bar Argor S.A Chiasso Kilo Silver Bar
These are great bars. I bought them new from APMEX a couple years ago. Not sure if they're still made or not.
Out of stock right now...but these are usually available... http://suissegold.com/bullion/silver-bullion-bars/suisse-gold-silver-1/suisse-gold-cast-bars
