Gold is worth exactly 10 times what silver is worth? There is no historical basis for making gold so inexpensive. What is YTU's specific explanation for gold's value dropping so much when silver's value also did not experience a consequent drop in value?
Platinum is worth 10 times what gold is? How did platinum soar so when gold dropped in value? There have been times where gold has sold for more on the open market per ounce than platinum (and platinum has sold for more at times, as well).
Iridium is worth 10 times what platinum is? What? Platinum (1209) may be almost twice what gold (614.75) is today, but iridium (360) is only a little more than half what gold is.
If you want an expensive commodity metal, try rhodium, 4540/ounce today.
(The above prices were pulled from www.thebulliondesk.com/. If you enter "gold platinum iridium rhodium ask bid", this is the website that is at the top of Google's search list.)
D&D seems to have no problem setting up such easy to remember ratios as that.
</font>[/QUOTE]D&D, in all its various gold-using fantasy incarnations, is just that, a fantasy setting. There must be a certain level of basic verisimilitude, but a good explanation will usually suffice to overcome the assumptions of the real world.
Such as race X valuing silver above gold for because it has undead slaying properties; but even this requires its consequences, with silver more common than gold, this would mean that outside parties could "buy out" the race's nations, unless silver were more rare.
A Science Fiction setting demands considerably more attention to verisimilitude and realism. (And yes, SF has a whole series of conventions that go along with it about what "impossible" things, like FTL travel (etc.), may be considered realistic and acceptable. Currency oddities are not one of those things, at least IMO.) Any explanation that is needed to overcome the assumptions of the real world must, of necessity (also IMO), be more substantial than any explanation that would suffice in a Fantasy setting.

Rhodium maybe worth a look, just so long as its not toxic or radioactive.
The metal is used to plate jewelry (among many other things), so bullion/coinage isn't going to be a problem in the toxicity or radioactivity department. (Rhodium is a platinum group metal.)

You appear to be making the absolute assumption that asteroids are planetary core fragments.
At least for the asteroids in Sol system, this does not appear to be the case.
I'll give you that canon does assert that many asteroids belts are the results of Ancients War activity destroying worlds.
However, the majority of core fragments are going to be (if you accept classic notions of Terra's, and therefore similar worlds', cores) nickel/iron.
Having a world blown up is going to fling the majority of the planet's former mass out of the solar system (IMO). As for the total amount of core fragments that remain behind and happen to contain precious metals in sufficient amounts of economically exploitable concentrations, well, I just do not buy that there will be a "massive abundance" of these types of asteroids, so often, in so many systems, that their output will be able to supply the hypothetical metal-backed economy that the Imperium would require.
However, I do fully admit that there are such asteroids in world-shattered belts. I have described starsystems IMTU where minining activities occur on such asteroids. Just not in sufficient quantities to provide for an Imperial metal-backed economy.

I'd say you can structure your metals coinage system however you like. (In an actual game, it would largely be color, anyway.)
You might want to consider the effect on tramp freighter trade that would occur if such freighters have to use up actual freight dTons moving the ship's cash-supply from system to system.
Personally, I wouldn't make iridium more valuable than gold.
-------------------------------------
The volume of money flowing through the Imperium annually is in the quadrillions of credits. The USA's current economy in 2006 looks like a rickety stool beside an orbital elevator in comparison. The USA's economy couldn't hope to be backed directly by metals by a huge amount.
I suppose it might be posited that gold could exist in sufficient abundance to back the Imperial economy, but it would be difficult and expensive to transport, secure, and use.
People didn't abandon metal coinage for significant denominations of currency in favor of paper for no reason. Current attempts to reintroduce dollar coinage in the USA have not been considered successes.
