Question as to value

I am currently working on restoring a 67 912, my first. I am not interested in concours, per se, I want to enjoy my vehicle while preserving as much of it's originality as possible.
Heres the question though, I have an original Blaupunkt am only radio that is in working condition. I intend to put something more modern in, for my listening pleasure. Is there any value to this radio to the true concours participant? If so what's your estimate, I'd like to sell, but don't want to over or under price it.
Thanks for any opinions

Yes and it depends on condition. You may find a price here, oldautoradio.com/
