Disney Lucasfilm has started a high end prop replica store, the Ultimate Studio Edition line made by Propshop at Pinewood Studios, in an attempt to be the most accurate prop replicas ever (or the most expensive, you choose).
Currently the line is just from The Force Awakens and exclusive to the USA. They'll ship in crates inspired by actual screen used props, and the COAs will have an authentication chip in them.
Prices start at $1250 and go to $3500. Some are limited to just 500 piece runs.
