If it is an original nova rear, I have seen them go for more than 1500$. If it was cut down to fit a nova, with good gears and a locker it is still worth 1000$. Hot item, people will stand in line for a 12 bolt.
I had a 12 bolt from my 63 (the 12 bolt was transplanted I know!). The stamps on the housing, the axle tubes, and the posi unit matched mine to a 66 Chevy Nova...I sold it on ebay and got 1500 for it. I even double checked to see if the axles tapered at the end and they did!
What I would do is grab all the codes off of it (housing, posi unit, axle tubes) because everyone will be asking to know! If you have a Nova rear...then dont take less then 1200 depending on what shape it is in. To sweeten my deal I sold the leaf springs (stock monoleaf) and shackles for it!
Good luck...and if you need any clarification on any of the codes just let me know!
Here is the codes off of my 12 bolt:
