For silver bullion I would consider CEF which is a closed end fund that trades in Canada and the US and holds around 55% gold, 45% silver. It is more conservative I believe than GLD or SLV allowing audits and holding PM in Canada. The premium has, however, gotton a bit high with yesterday's closing price it was 9.8% in the US. Therefore if you are interested you may want to keep your eye on it and scoop it up when its a bit lower.

It has a new sister that just holds silver and you can check out the site at www.silverbuillontrust.com. It trades in Canada under SBT but I am unable to find it here in the US.
