Like I said few times before, Gold has tremendous potential to the upside, when (note the absence of "if"

) reintroduced as a currency. Or even when the investments houses start to allocate at least a portion of their portfolio into gold. Big boys play.
Silver... well, it always was "poor man's gold" - anyone sees the upside potential here, when average Joe the sixpacks start trampling over each other, to get their hands on some hard currency, once the paper money collapse begun? Can they afford gold - expensive enough today, in paper terms - and how expensive it is going to be, before they realize what's going on?
Therefore, I believe in 50/50 allocation of the two, in dollar terms. Agree that silver has more potential, and is further away from being manipulated into death, once sheep recognizes it's worth. But it is also hard to estimate gold's potential to the upside, if/when financials start panicking, realizing that all their assets might get nice percentage returns, in dollar terms - the only problem is, that dollar will be going down even faster, in real terms. And today, gold part of the portfolios are just tiny, percentage-wise, comparing to paper (dollar-denominated) assets. AFAIR, I've seen estimates, that about 2% (total) portfolios consist of gold, on average. If we see, say, even just 5% of portfolios (globally) redirected into gold, supply/demand would dictate 2.5 times rise in gold prices. And it would be still TINY portion of portfolios, IMHO - so the sky is the limit, once things start to happen.
Thus, I just think 50/50 Gold/Silver, in dollar terms, and don't loose sleep over it anymore - one way or another, it will be one nice slingshot, eventually.
