DISNEY XD CHANNEL NUMBERED PRINT PRE-2014

[LESTWEFORGET]

I found this framed print from the Disney XD channel show Star Wars Rebels which shows the concept images and designs of the character Chopper. It's #213 out of only 400 made and supposedly only given to TV executives and staff members who worked on the show. I think this is pretty rare as I only found two on the net with one sold in 2014 (sold for over $500) and a current one for sale on Ebay ($120). It's not something that I collect so I plan on selling it but not exactly sure what the actual value would be based on the spread of the prices I found. Anybody have an idea as to its' actual value or how I could accurately price it? Really appreciate any thoughts and hope everyone had a great Thanksgiving!
