I have
a post up on the corporate blog featuring a
Sharelynx log chart of the gold price.
There is also a very good video of why gold was (is?) favoured as money over other elements/metals in this post
The Science Of GoldAnd in response to this cheeky question from JR re that post "Is the Perth Mint claiming that gold is money due to its unaltering quality!?", the answer is No. The "What others are thinking" category on the corporate blog is for non official views and maybe the wording "gold is all but unrivalled as the outstanding candidate for money" could have been a bit more qualified in retrospect. :)
