Buy Maples instead of bars or rounds. Maple is 9999 pure and one of the cheapest bullion coins. Not particularly stunning and often marked, chipped or stained - not always though. Treat them as currency i.e stack of silver by weight and easy to shift. They are best bought as a tube of 25. Collect the wildlife series for posterity - issued so far the Wolf, Grizzly and about now the Cougar. Buy each issue to form a set in time and perhaps they will become attractive to collectors in a few years.
Reckon you are in a winning position. Customs will definitely be watching out for you now. If passing through the UK en route I could perhaps save you carrying all that stuff round the world if the price was right.
