I am playing a stealthy thief. When I sneak up to someone, before killing them, I try to pick their pockets to level Pickpocketing.
A lot of people when I browse their inventory have 3 or 7 Gold in their inventory. So I choose to not take the gold, but something else valuable.
After killing them stealthily, when I raid their corpse, the gold level is at about 20 gold.
I also tried pickpocketing their 3 or 7 gold, and their corpse still yields 13-15 gold.
People with higher gold levels like bosses, might carry 50-100 gold, and once pickpocketed, upon death their corpse does not yield any more gold.
I would like to know out of curiosity where this extra gold is coming from and why does it not show when I am browsing their pockets?
