Value Question- Creek 5250SE

My hope this an appropriate place to ask, my apologies if not.  Looking to list my Creek 5250SE.  Clean and original.   I purchased it from the original owner.  Is missing two of the screw lugs (for spade connectors) from one of the speaker terminals, other 6 are there.   I use banana plugs so never an issue.  Outside of that I would say 7.5... few very small nicks and minor blemishes. 

What would be a fair asking price?   Can not find another one for sale or any past sales to use as a starting point. 

Thank you in advance for you help and time.
