I have never seen any 3po prototype case sell in the $8-10k range especially the clear one which is one of the most common. I have an early sample gold prototype case and bought that in private! never seen one for sale either. Mostly the ones for sale are the clear or white ones and usually sell up to the $3-4k but used to be a lot cheaper. The gold Vader cases do sell for a lot more. Curious do you own the Gold Vader and Silver prototype cases?
