What do you do with figure pack-ins?

POTF came with freeze frame slides and flashback cards. Late POTF and Episode I came with Commtech chips. POTJ came with Force Files. Some Saga, OTC, Episode III, TSC, and TAC came with bases and display stands. TSC also came holographic figures and TAC also came with coins.

I have the coin album but for the rest of these, whether released by Hasbro or not, how do you keep these packed-in items?
