Selling an expensive collectable

As sales have dropped for my cheaper items, I have been listing some of my rare, hard to get collectables. However, I am reluctant to list those in the $1000 and up range. This is due to my fear of them falling into the hands of ebay scammers who make false claims. These harder to get items mostly end up in the US. I've been burnt once before and obviously wish to avoid this happening again.

 

Do readers have srategies to lessen this possibility.
