When moving the best/least expensive motto in time and money is...
How many do you "need"? Or Will I ever "use" this again.
With a collection or emotional attachment this is a bit more of a grey area. Ultimately, you should look for a way to reduce the stress of a move and spread it out over time. i.e. sell the things you don't "need" or can easily replace once you have moved or move them ahead of the move with some form of moveable storage.
Once you have decided to part with something it might also be worth it to know if it could be donated to someone that will use it. It is worth pondering but not stressing over. The benefits of giving something meaningful should never be overlooked. If you don't know what I mean then try it.
