Individual gold pieces (A.K.A. Septims) can be found, coin purses can be found, gold can be found within containers, pickpocketed from living persons, and gold can be stored from the player into a container (or pickpocketed onto a living person). However, once individual gold pieces or coin purses are looted, I know of no way to drop individual gold pieces or coin purses, as they are converted into a player value, rather than being or remaining a physical object with which one may interact.
Particularly without the console or mods, is there a way to generate individual gold pieces that can be moved and looted?
