I'm not sure that currencies are really a good vehicle for savings. They appreciate and depreciate against each other and can be quite volatile.
You did alright with the Kroner, I remember when 7DKK/1USD was the norm 10 years ago. Keep in mind that it is loosely pegged to the Euro. The Swiss Franc has always been seen as a safe haven currency, but their central bank is doing some weird things like speculating with their reserves. The Ruble lost a lot of value against the Dollar in recent years, but I would think there's a lot of room for it to bounce back.
Gold and silver are pretty low right now, in my opinion. Silver is the more liquid asset.
I still think USD is probably the safest asset right now, though.
