Rarest LEGO Items

Here is a new exhibit for the Modular Natural History Museum. Starting with three displays, the newest exhibition contains three of the rarest unlicensed LEGO items. On the left are the LEGO minifigures from Jupiter, which are 1/1 and were in space! A Mr. Gold from Series 10 is in the center, with a case to protect it. Only 5,000 were ever made. At the end, we have the 14 karat gold 2x4 LEGO brick, which were given out to LEGO employees.

Thanks for reading, and what items do you think belong in this exhibit?
