One more option I was recently toying with is to ship it to a vault temporarily.

For example, if I were headed on vacation for a few weeks (or even months), and I had a package that might arrive while I'm out, I could always just tell the shipper to send it to the vault while I'm out. Then after I get back, I could have the vault gather up all of those pieces that arrived while I was out, and ship them to me.

Along these lines, I suppose if I was going to be out of the country for a few years, then this might be one of the times when I would consider using a vault so as to not have to fuss with schlepping my collection around the globe and/or hoping that a storage unit will be sufficient protection. Especially if you want to keep adding to your collection while you're out. Just have the sellers ship it to your vault account, and they'll hold everything while you're globetrotting.

Of course, you would need to make sure that you trust the vault operator, and make sure that they're not going to hit you with fat fees for using them in this fashion.
