27t roadster custom build

Hi everyone. I'm hoping I can get some help here. My dad built a custom 27T and almost finished it before he passed away. Just a few minor detail things that need done.  It has a Chevy 383 stroker and a Powerglide transmission. It also has parts from 17 other cars I think he said. My mom would like to sell it now and I have no idea even what it would be worth. I know he put $10,000 into the build. If anyone could give any idea what it might be sold for it would be very much appreciate. 
thanks

Steel body or glass? What's the frame? Full gauges all working? Disc brakes?  The price on a car like this is all about the details. That said, I've seen T buckets go for anywhere from $8000 to $25,000 depending on the details and quality of the build. 

In reply to Panhandler :

Fiberglass body and the frame came with the kit. All the gauges work on the dash and it does have disk brakes.
