Does Oblivion have a 'Drop' command? I know FO3 does. When you would get the nugget, just add one, and then drop one.
Hmm, not that I know of. Did a quick search through the OBSE docs too and didn't see anything like that. What exactly does this command do in FO3?
Heh, yes there is: "http://cs.elderscrolls.com/constwiki/index.php/Drop".

But, I′m not sure if you can use it on container. But note that once you get the container ref using getcrosshairref, you can also just use "placeatme" to place the item at the container. You can even get the ref of the placed gold piece, like this: "set myref to containerref.placeatme mygolditem 1,0,0" for example.
Yes, there′s talk about placeatme causing bloat, but in this case, cause it′s inventory item meant to be picked up, the ref should be cleaned out when picked up. The problems arise if a mod places an activator after activator to the game world, to for example cast spells, cause those can′t be picked up and disabling wont delete them. So just use placeatme, it′s a great function if used for the right purposes.

EDIT: added "and"
