Watch it with safety boxes. A year back the Police hit a major safty deposit box in London and ripped EVERYONE open. Said they were looking for drugs/kiddie porn/ terrorist papers etc, basically the usual shit. No dount they caught some wrong people but everyone else who had valuables had to prove where they came from before they got them back. They can do basically what they like these days all under the cover of 'national security'. 2 or even 3 safes in the house are the way to go. Then if some punk puts a gun to your head asking where the safe is you point to the one with $1000 in and some fake rings/bracelets etc.
that's right - in the 1930s, not only could your bank have closed, you could NOT open it without an IRS agent present Because in the time that the contents had sat there in the dark, the government had declared that any gold put there belonged to the government, not the owner i dont think anyone should ever forget that - contents are not 'safe' unless they are safe from ANYONE who thinks 'you know, that really belongs to me more than the person who put it there'
If you are going to hold assets outside the US make sure its a country that has no tax treaty with the US. this means that country is not used to comply with uncle sam usual BS
