How do dragons move their hoard?

[Creed]

Well, first, there's the cumbersome task of converting your hoard into large, non-consecutive gold coins. Magic items, pieces of art, potions, and assorted furniture make for great treasure density and sprawl, but whenever you move it's a good idea to liquidate all those assets into the currency of the country you're moving to. You never know whose family heirloom or lich's phylactery you've got sitting around, you're better off cycling all that out into currency.

Next is moving the treasure. I know what you're thinking, the volume of all that gold? Very difficult to move. I say no. You see, when you sold all your magic items, you held on to all your bags on holding, which you just load up with gold, then fly to your destination.
