Are collectibles list always changing?

[Hycinthus]

The list changes daily. Check you timers window to see when the reset time is in your time zone. There's no way to influence what shows up in the list, it's random. Best thing you can do at this point is hold on to your items and keep an eye out for them to show up again.

Thank you for this insight. So it's a 24 hour reset yes? I'll just keep an eye daily.
