Thank goodness they don't. Imagine your house burning down (or worse, you getting robbed and killed) when your net worth is in bearer bonds under your mattress.

(is that right? That it's due to a new haul of silver? I thought it was because of higher margin requirement in asian exchanges; but I could be wrong - I'm don't pay real time attention to the metals too much). Assuming you are right (about the haul being the reason), your holding just got devalued (finding new silver == fed printing money). So not sure why silver is a safer store of value.
In addition to Greek and PIIGS default another worries are 1) Israel gets attacked by several nations and we are talking mini world war with nukes "on the loose and in the use". 2) US attacks Pakistan and China and Saudi Arabia get involved. China getting in means WWIII and then all the fireworks get on the go. 3) USD dives into the ground and Chinese, Japanese, EU demand physical US assets in return. Another scenario for WWIII. RATS and DEMORATS have run this world into the ground. PURE EVILNESS!
