Ahoy!
This suggestion has probably been made before, but it'd be cool if every once in a while when defeating a gold skeleton they dropped some piece of treasure as an extra reward.

They're literally made of treasure, and can take a while to kill if they're up on a mountaintop far away from water. It'd be cool if one would drop a gilded chalice or something of the like every so often as a little bonus for your effort.

It just makes sense that you'd profit from killing something MADE of gold. And who doesn't want more ways to get treasure?
