I think that's part of the issue, but I think the main thing is that the extra granularity provided by the coins simply isn't required. Coins are a hassle to use (And also fairly expensive, since a coinpress certainly isn't free), and even with the precious metals the value per coin is simply too low to really bother with it. Other goods (Avu has mentioned bricks somewhere) can fill the function of providing that extra granularity whenever its needed. (In the case of gold and silver the issue might actually be the opposite. They are easier to sell on a per-nugget basis than as coins, as they are only useful as whole nuggets, but also much to expensive, thus non-granular, on a per nugget basis to actually be useful as a medium of exchange.)
I also think that the economy is so relatively non-complex (limited number of goods types, limited number of relevant dimensions to the goods types, essentially just type and q) that a more generalized medium of exchange isn't really required. Goods are easy to compare anyway. Simpler forms of barter work quite well.
I think gold and silver could have the potential to monetarize the economy by virtue of being q-less. The one thing that makes them useless in that function presently is probably that gold and silver are effectively expended qua gold and silver as soon as you turn it into jewelry/symbel stuff. I believe that one of the historical functions of precious metal jewelry was to be able to carry something valuable on ones immediate person, quite simply. If jewelry could be turned back into nuggets, I think it could be much more useful as a trade medium, but given the present implementation of jewelry and bling that would just turn silly.
