I seem to recall a previous thread waaaay back at the start of 3e that discussed coinage. I think the consensus was that gold coins tended to be about the size of a US penny, depending on the metal and purity. Since the game assumes 100% pure metals (or that minted gold is as pure as "raw" gold), a solid gold penny would be about 8.5g or about 50/lb.
Platinum is denser than gold so you'd get something smaller than a penny but not quite a dime, while silver and copper would be more like thick nickels.
