Silver will never be worth more than gold. However, if historical markets are anything to go by, the Gold-Silver ratio should be about 15. That would mean that you could buy an ounce of gold with 15 ounces of silver. Currently, the ratio stands at 46
The ratio tends to decrease back towards historical levels in a bullish precious metals market. We are currently seeing gold and silver beat records month on month. Whether this will continue, I'm not sure - but I suspect it will. There is quite a large supply gap between bullion, and promissory contracts for both gold and silver which is verging towards a crisis.
I agree that silver is probably a better investment than gold right now, as long as you are buying real cold metal which you can hold in your hand. Buying paper precious metals, is in my view quite reckless in the current climate. However, silver bullion attracts VAT in the UK which rather scuppers this plan.
