Comment 9 for bug 780364

It would be great to be able to manage also precious metals (such as gold, silver, etc.), the same way currencies are managed (this is actually the way I am currently doing, but I have to manually change the price regularly while currency are automatically updated).
Of course, I believe users might have different preferences on the units to use (g/oz/etc.), which would make it slightly different than a normal currency.
