Transporting an entire collection

[Hkexpat183]

Hoping to get some advice from people that may have moved around the world a bit.

I currently live in HK. If I were to uproot and move my family back to the states what is the best and safest way to transport my collection?

My initial thought would be to put the collection in my case that holds 12 watches and just put it in my carry on and then ship the boxes and papers separately.

The only risk with this being stopped at customs.

Open to any suggestions or thoughts. Be great to hear other methods from people who have had to make a move back to states.

Thanks.
